Mathematical design of soft magnetic materials

Prof. Ananya Renuka Balakrishna, PhD, University of Southern California, presents a strategy for the design of ferromagnetic materials with exceptionally low magnetic hysteresis, quantified by coercivity. It predicts that cubic materials with large saturation magnetization ms and large magnetocrystalline anisotropy constant κ1 will have low coercivity on the order of that of Permalloy, as long as the magnetostriction constants λ100, λ111 are tuned to special values. 01:48 Introduction of Prof. Balakrishna 03:24 Presentation 05:33 Agenda 06:16 How do microstructural instabilities & material constants shape magnetic hysteresis? 36:33 Can we crystallographically engineer magnetic materials to mitigate fatigue? 44:53 Acknowledgements 45:20 Q&A 56:00 Links
