Organization
Magnetic thermal management materials (MTMMs) are a new class of functional materials that use magnetism to convert, control, and transfer thermal energy. Creating these materials requires harnessing spin physics for thermal engineering applications—and this, in turn, requires transcending the traditional barriers that separate various disciplines of science and engineering. This project, based at Japan’s National Institute for Materials Science (NIMS), includes researchers from a wide range of backgrounds—including condensed-matter physics, metallurgy (permanent magnet development), nanostructure analysis, thermal measurement, and heat-transfer engineering—working in concert to create MTMMs.

Thermal Management Principle and Functionality Development Group
(NIMS & The University of Tokyo)This group oversees the tasks of proposing structures and identifying new principles for the three new types of MTMMs our project is working to create. This group collaborates organically with each of the other groups and works on synthesizing materials, characterizing physical properties, and constructing modules.
