Abstract
The magnetic properties of polycrystalline Nd 1− x Gd x Mn 2Ge 2 (0≤ x≤1) compounds have been investigated by means of X-ray diffraction and measurements of the DC magnetization. All compounds crystallize in the ThCr 2Si 2-type structure with the space group I4/ mmm. Lattice parameters and the unit cell volume obey Vegard’s law. The samples with x≤0.6 are ferromagnetic and have spin reorientation temperature. In the case of 0.7≤ x<1, samples are ferrimagnetic with compensation point and reentrant ferrimagnetism is observed for x=0.8 and x=0.85. As a result, the magnetic phase diagram has been constructed.
