Paul M Haney (Fed)

Paul Haney is a Project Leader in the Nanoscale Processes and Measurements Group in the Nanoscale Device Characterization Division. He received a B.S. in Physics and Mathematics from The Ohio State University, and a Ph.D. in Physics from The University of Texas at Austin. His thesis consisted of first-principles calculations of electron and spin transport in magnetic and antiferromagnetic multilayers. Paul joined NIST as an NRC Postdoctoral Research Associate in 2007, where he worked with Mark Stiles on the theory of spin transfer torque in the presence of spin-orbit coupling. Upon his appointment as Project Leader in 2010, Paul worked on the theoretical modeling of polycrystalline photovoltaics for several years.

Paul’s current research interests encompass spintronics and topological physics. Spintronics studies the interplay between electron transport, quantum degrees of freedom like spin, and magnetic order. This field of study has direct applications in next-generation electronic applications, such as magnetic random access memory. Paul’s recent work in this area utilizes a combination of analytical and computational approaches to uncover and examine novel spintronic phenomena. His interest the topological materials is motivated by their robust spin and transport properties, which can be utilized in next-generation electronics and metrology applications. A particular focus of this work is the study topological materials for electrical standards applications.
