Magnetic anisotropy of ultrathin Pd4Co(111) film by first-principles calculations

The PdeCo alloy is a suitable candidate for the perpendicular magnetic recording and related applica-tions. However, no research is available to clarify influences of local structures on the magnetic anisotropy of the PdeCo alloy. Therefore, in this work, we studied the effects of Co arrangement on...
