Talk: Magnetic nanowires can have many names: bits, sensors, heads, artificial cilia, sensors, and nano-bots. These applications require nanometer control of dimensions, while incorporating various metals and alloys. To realize this control, our 7- to 200-nm diameter nanowires are synthesized within insulating matrices by direct electrochemistry, which negates sidewall damage such as that caused by lithographical patterning of vacuum-deposited structures. Our nanowires can easily have lengths 10,000x their diameters, and they are often layered with magnetic (Co, Fe, FeGa, FeNi, Ni) and non-magnetic (Ag, Cu, Au) metals as required by each application. This talk will reveal synthesis secrets for nm-control of layer thicknesses, even for difficult alloys, which has enabled studies of magnetization reversal, magneto-elasticity, giant magnetoresistance (GMR), and spin transfer torque (STT) switching. In addition, this lithography-free synthesis yields 10-nm diameter nanowires that have resistivities of only 5.4μΩ.cm (nearly that of bulk copper) due to negligible sidewall roughness. Therefore, these nanowires will mitigate the ITRS Roadmap’s “Size Effect” Grand Challenge which identifies the high resistivities in small interconnects as a barrier to continued progress along Moore’s Law (or better). Ten-nm diameter trilayers of [Co(15nm)/Cu(5nm)/Co(10nm)] have also met or surpassed all of the criterion for the world’s smallest read heads with 30 Ω resistance and 19% magnetoresistance. High magnetoresistance is also possible in other multilayered nanowires that exhibit excellent properties for mulit-level nonvolatile random access memory (RAM) using STT switching at very low current densities (100kA/cm2). If the insulating growth matrix is etched away, the nanowires resemble a magnetic bed of nano-seaweed which enables microfluidic flow sensors and vibration sensors. Finally, we have incubated various nanowires with several healthy and cancerous cell lines, and find that they are readily internalized by all cell types thus far. Careful magnetic design of these “nano-bots” enables external steering, nano-barcode identification, and several modes of therapy. In short, by the end of this talk, I hope you will be convinced that magnetic nanowires can and will revolutionize hard drives, RAM, and cancer treatment.

Speaker Bio: Dr. Bethanie Stadler works on the integration of nanomagnetic and photonic materials with a variety of platforms to allow the development of practical devices and systems. This includes magnetic nanowires for magnetoelectronics (including hard drive heads), microfluidic flow sensors and actuators, acoustic/vibration sensor applications, and cellular biomarkers. In photonics, Stadler works on the integration of magnets, magneto-optical garnets waveguides, and nanostructures for magnetophotonic crystals with semiconductor platforms for isolator and sensor applications.

Stadler received her PhD from MIT in 1994 and her B.S. from Case Western Reserve University in 1990, both in Materials Science and Engineering. She held a NRC postodoctoral fellowship at the Air Force Rome Laboratory before joining Electrical and Computer Engineering at the University of Minnesota, where she is also on the Graduate Faculty of Chemical Engineering and Materials Science. She has been awarded the NSF CAREER award and a McKnight Presidential Fellowship. Stadler has served both as Director and Secretary of the Materials Research Society, and has been asked to teach for the IEEE Magnetic Summer School in Chennai India and in Assis Italy.

Upcoming Meetings
January Section Meeting: Is scheduled for Tuesday, January 17th at noon at Promega Biotechnology Center in Fitchburg and will be a talk by Bethanie Stadler who works on the integration of nanomagnetic and photonic materials with a variety of platforms to allow the development of practical devices and systems. This includes magnetic nanowires for magnetoelectronics (including hard drive heads), microfluidic flow sensors and actuators, acoustic/vibration sensor applications, and cellular biomarkers.

January Life Member Affinity Group Meeting and Tour: The LMAG group has arrange a talk about the UW-Madison Stellerator Project and a tour of the HSX Labratory for the evening of January 31st. Dr. David Anderson will give the talk. HSX is a modular coil stellarator optimized for quasi-helically symmetry located in the Electrical and Computer Engineering department at the University of Wisconsin-Madison. Plasma physics research goals include investigation of transport, turbulence, and confinement in a quasi-helically symmetric magnetic field. Please check the event listing here for details about parking and the talk room location. At the time of the Newsletter, those details were not available.

IEEE/Badger Amateur Radio Society Joint February (Tentative) Meeting: Many of our members got our start in Electrical Engineering as a hobbyist, or a Ham. The UW-Madison Badger Amateur Radio Society is in danger of being de-listed as a student club. The ARRL has announced a program called “Ivy + Amateur Radio” — to boost college and university Amateur Radio club interest, membership, and activity. There will be a local joint meeting of the Madison IEEE Section including the UW-Madison Student Branch and BARS with the express intent of rekindling interest in BARS. For more information see the ARRL Announcement and the Badger Amateur Radio Society W9YT link.

February Section Meeting (Tentative) -- Dr. Thomas Jahns will be giving a talk on the electric grid, distributed energy and micro grids. It will be held Thursday, February 16th starting with a social time at 5 pm and a 5:30 presentation. somewhere on the UW-Madison campus. Check the IEEE-Madison Section event link later for details.

Sector67 Announces a New Permanent Home
The IEEE-Madison Entrepreneur and Consultants Network holds regular meetings at Sector67. Sector67 is working hard to move to a permanent location on the near east side. They have identified a site at 56 Corry St just a few minutes away from their existing location and have announced a capitol campaign to purchase the building. So far, Sector67 has raised $450,000, 75% of the $600,000 capital campaign goal and over halfway to the $750,000 stretch goal. If you or you company are interested in donating, please visit their Donation Page. The donation page has a link to a great video starring John Wiley.
