Ga magnetic polarization in Mn3GaC under high pressure probed by Ga K-edge XMCD
2005
To study pressure-induced ferromagnetic state in Mn3GaC perovskite, we have performed x-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD) spectroscopy at the Ga K-edge under high pressure up to 29.4 GPa at room temperature. Ga K-edge XMCD was observed under pressure ranging from 4.5 to 29.4 GPa and results indicate that the Ga atom is magnetically polarized under high pressure. From the XMCD spectral profile, it is suggested that the pressure-induced ferromagnetic state has a canted ferromagnetic structure.
