Abstract

We present the structural and element specific magnetic properties of Co₂MnSn and Co₂MnSb thin films grown on GaAs (100) substrates using pulsed laser deposition. X-ray magnetic circular dichroism (XMCD) spectra were measured for 400 A thick films at the L_2,3 edges of Co and Mn. Element specific moments for Co and Mn in Co₂MnSn were calculated from the x-ray absorption and XMCD spectra using the XMCD sum rules. The ratios of orbital to spin magnetic moments for Co and Mn were calculated for Co₂MnSn and Co₂MnSb.
