HIGHLIGHTS
- who: Xinglong Ye from the Institute of Technology, Eggenstein-Leopoldshafen, Germany have published the paper: Giant voltage-induced modification of magnetism in micron-scale ferromagnetic metals by hydrogen charging, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
- what: Using micrometer-sized SmCo5 powder, the authors show that it is possible to reversibly charge and discharge the material with hydrogen atoms by applying small voltages.
SUMMARY
The change of oxidation state and crystal_structure in the ultrathin Co layer permits to modify its magnetic properties. The modulation of coercivity reaches only a few tens . . .
