Michael E. McHenry is Professor of Materials Science and Eng. (MSE), with an appointment in Physics and Biomedical Engineering at Carnegie Mellon. He graduated with a B.S. in Metallurgical Eng. and Materials Science from Case Western Reserve in 1980. From 1980 to 1983 he was employed as Process Engineer at the U.S. Steel Lorain Works. In 1988 he earned a Ph.D in Materials Science and Eng. from MIT. He was a Director's Funded Post-doctoral Fellow at Los Alamos Lab from 1988 to 1989. He has expertise in the area of nanocrystalline magnetic materials including soft magnetic nanocomposites, faceted ferrite nanoparticles and materials for power conversion, biomedical, energy and data storage applications. His research involves rapid solidification processing, plasma and solution synthesis of nanoparticles, magnetic field of processing materials, structural characterization by x-rays and electron microscopy and magnetic properties characterization as a function of field, temperature and frequency. He directed a Multidisciplinary University Research Initiative (MURI) on high temperature magnetic materials for aircraft power applications and led an ARPA-E program in magnetic materials for power electronics. He served as Technical Evaluator for the NATO AVT-231 Specialists Meeting on "Scarcity of Rare Earth Materials for Electrical Power Systems". Brussels, Belgium, (Oc. 13-15, 2014) and continues with a NATO team considering implications Rare Earth Element scarcity for NATO countries. He has served as proceeding Editor, Publication Chair and a member of the Program Committee for the Magnetism and Magnetic Materials (MMM) and Intermag Conferences. He has published over 350 papers and owns two patents in the field. He has co-authored, with Marc DeGraef, the textbook “Structure of Materials”, Cambridge University Press, 2007 with a second edition in 2012.

The research interests of M. E. McHenry involve developing the understanding of the magnetic property of materials. This includes interfacing theoretical and experimental studies of magnetic materials. Superconducting materials are included since the current carrying capacity of superconductors is a magnetic property (i.e determined by the ability of these materials to pin magnetic flux). He initiated a program to investigate fundamental magnetic properties of magnetic surfaces, interfaces and multilayers. He has had past interest in the magnetic properties of icosahedral structures includes the study of magnetic quasicrystals and the magnetic and superconducting properties of fullerenes. His recent efforts have been in magnetism in nanostructures. He was the PI on a MURI program studying high temperature magnetic materials which was followed by his recent development of soft magnetic materials for motor and power electronics applications with Magnetics, A Division of Spang and Company. He studies magnetic materials for electromagnetic interference shielding with Northrup-Grumman. He has initiated studies fundamental properties of magnetic oxides for applications in high frequency inductive components with the Penn State Electro-optics Center. He has also initiated research in the area of magnetic nanotechnology for applications in medicine including thermoablative cancer therapy, tagging of tissue scaffolds and magnetoelastic ferrogels and polymers. He studied high frequency heating of magnetic nanoparticles for solder reflow with Intel. Magnetocaloric cooling applications were explored with Ferrosolutions. He studied magnetic alloys for Westinghouse Bettis. He studied magnetic materials and sensing for extraterrestrial exploration in collaboration with the Spanish space agency, INTA. His work in power electronics has led to the awarding of an ARPA-E grant in 2011 to study magnetic materials for solar photovoltaics. He has performed as subcontractor on a DOE SunLamp Program, an Eaton (DOE) NGEM program, a NCSU (DOE) solid stae transformer (SST) program and recently awarded a DOE AMO program to study Metal Amorphous Nanocomposites in motor applications. He consults for Northrop Grumman, WPAFB, Carpenter, and is a specialist for NATO Advanced Vehicle Technology (AVT). He is a Lecturer for the NATO AVT Series of “Rare Earth Criticality.”
