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...

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 the magnetic anisotropy of ultrathin Pd4Co(111)film with 20% Co content by using the density functional theory calculations. We found that a Co monolayer in the surface layer of the ultrathinfilm offers a large in-plane magnetic anisotropy while the Co atoms mixed inside the Pd matrix exhibit the perpendicular magnetic anisotropy. Notably, a Co monolayer beneath the surface layer of the Pd matrix maximizes the perpendicular magnetic anisotropy up to 1.85 erg/cm2. Electronic properties were also analyzed to clarify the magnetic anisotropy of the ultrathinfilm. |
