Synthesis, Magnetic Properties, and Modeling of Magnetization Reversal of an Artificial Antiferromagnet Based on L10-PdFe
The static magnetic properties were experimentally studied and magnetization reversal was modeled in an epitaxial thin film of the L10 phase of the PdFe compound and the PdFe/W/PdFe heterostructure on MgO (001) substrates. It was shown that the PdFe/W/PdFe heteroepitaxial structure at an α-W layer thickness of ∼0.7 nm is an artificial antiferromagnet with perpendicular magnetic anisotropy and an exchange integral of \(J \simeq 1.7 \times {{10}^{{ - 3}}}\,\,{\text{J/}}{{{\text{m}}}^{2}}\). Micromagnetic modeling of the equilibrium domain structure and its evolution in an external magnetic field made it possible to satisfactorily describe the magnetization reversal curve of the studied thin-film heterostructure.
