Charge Density Wave Stabilized Magnetoelastics /Research Topic: Magnetic Materials

Abstract

The research aims to understand and further develop iron-based ultra-soft alloys featuring a linear, isotropic and non-hysteretic magnetization curve and significant magnetostriction. The investigation have revealed unusual domain structures indicative of internal magnetic and elastic closures In Fe-Ga (published in Nature) and similar features in FePd in the vicinity of the cubic-tetragonal phase transformation (published in Science Reports, manuscript attached). Future investigation will concentrate on Fe-Al, Fe-Ge and FeCoZn. To that end we have developed a single crystal growth approach which inhibits Zn loss. Preliminary results on CoNiZn indicate that the magnetocrystalline anisotropy is very as well, i.e. it is ultra-soft.
