To achieve a large terahertz (THz) amplitude from a spintronic THz emitter (STE), materials with 100\% spin polarisation such as Co-based Heusler compounds as the ferromagnetic layer are required.

From magnetization measurements a saturation polarization of 0. 86 T at 10 K was detected, together with a uniaxial magnetocrystalline anisotropy constant of 1. 18 MJ/m$^3$, and the Curie temperature of $T_{\rm C}$ = 359 K. These magnetic properties make Co$_3$Mn$_2$Ge a very promising material as a rare-earth free permanent magnet, and since we can demonstrate that magnetism depends critically on the amount of disorder of the Co and Ge atoms, a further improvement of the magnetism is possible.

Owing to the formation of magnetic clusters at lower field a field-induced crossover from long-range to short-range magnetic interaction was observed in the compound.
