The intermetallic antiferromagnetic compound Mn2Au has been attracting considerable interest for antiferromagnetic spintronics due to its high Neel temperature and strong spin–orbit coupling. We report on the experimental investigation of the zero-

The interest of giving active functions to antiferromagnetic (AFM) materials in spintronics devices has been realized recently. Mn2Au is a high-Neel temperature antiferromagnet with large Mn moment, lying in plane of the tetragonal structure. To dete

In hard magnets, coercivity is not a material intrinsic property. Magnetization reversal is constituted by a series of local processes, of which the first, termed as “true nucleation”, takes place within a defect. An original analysis is proposed

In usual analyses, the coercive field of hard magnetic materials is related to the main phase anisotropy. This may be questioned since coercivity is not an intrinsic material property. In a recent paper, we have shown that a relation may be establish
