Professor Michael McHenry's team of researchers at Carnegie Mellon University have developed nanocomposites for applications with high permeability requirements and with needs for large inductions at high temperatures. Specifically they have developed soft magnetic alloys that exhibit high magnetic induction at temperatures above current operating ranges for commercial devices. Soft magnetic materials face demanding requirements from new, high-performance electronic and power distribution systems. The new systems must operate in high-temperature and high-frequency regimes that are inaccessible to conventional crystalline and amorphous magnetic materials. The need for increased energy efficiency requires reduced power loss from inductive components. Nanocrystalline magnetic materials hold promise for meeting these requirements without resorting to the trade-offs needed when using conventional materials.
