Abstract :
This study investigates the temperature-dependent magnetic properties of rare earth-transition metal DyCo4 alloy film using synchrotron soft X-ray magnetic circular dichroism (XMCD) spectroscopy. The ferrimagnetic alloy thin film is prepared by magnetron sputtering in an ultra-clean argon atmosphere at 1.5×10-3 mbar pressure and 300 K temperature. By applying the sum rules, the magnetic moment is determined from the transmission XMCD.
