Future Nanoscale Multiferroic Devices

UCLA Science Faculty Research Colloquium 2012-13

Greg Carman
Professor of Mechanical & Aerospace Engineering

Present day electromagnetic devices rely on magnetic fields generated by passing a current through a conducting wire; a discovery made by Oersted nearly 200 years ago. While extremely useful, this approach fails at small length scales and thus presents a major obstacle to the further miniaturization of electronic devices. Recent scientific discoveries show that a magnetic material’s intrinsic magnetization can be manipulated with an electric field. This innovation thereby overcomes the deficiencies associated with Oersted’s current driven system, especially in the realm of nanotechnology. Professor Carman will describe the ongoing multiferroic research, and the potential applications that this new approach has to offer the scientific and engineering communities.

Professor Greg P. Carman’s research is on understanding the multi-physics behavior of active materials such as piezoelectricity and magnetoelasticity. He is the Director of the new National Science Foundation Engineering Research Center focused on Translational Applications of Nanoscale Multiferroic Systems (TANMS), and is the Co-Executive Director of the Center for Advanced Surgical and Interventional Technology (CASIT) in the Department of Surgery at the University of California Los Angeles (UCLA). Professor Carman was awarded the “Adaptive Structures and Material Systems Prize” from the American Society of Mechanical Engineers in 2004.
