Circular Dichroïsm

Magnetic circular dichroism (MCD) spectra of La 1-x Sr x CoO 3 have been measured at Co 1s and 2p XAS, La 3d and 2p XAS. The contribution of the orbital moment to the total magnetic moment of Co ions became larger with the Sr composition of the La 1-x Sr x CoO 3 system increasing. There was no polarization of the 4f orbital in La but the 5d orbital in La was polarized by the hybridization between the Co 3d orbital and the La 5d orbital.

Circular Dichroïsm

The elemental magnetic moments of Co and Cr in CoCrPt films were investigated using xray magnetic circular dichroism (XMCD). The spin and orbital moments of Co was calculated using the sum rules; it was found that the magnetic moment of Co in CoCrPt films was dominated by spin moment contribution. The total magnetic moment of Co was found to be lower than that of bulk Co. Further, the Cr moment was aligned anti-ferromagnetically with respect to Co, resulting in a decrease of saturation magnetization (Ms) in CoCrPt films.
