Abstract:
The X-ray diffraction and specific heat measurements have been performed for the ferromagnetic compounds (MnCo)(1-x)Ge within the concentration range 0.02 <= x <= 0.035. The compounds possess the hexagonal Ni2In-type structure at elevated temperatures, while for the composition with x = 0.02 and 0.03 a spontaneous martensitic-type transition to the orthorhombic TiNiSi-type phase occurs at 283 and 221 K, respectively. We studied the entropy changes associated with the first-order structural transition and estimated the changes in magnetic, lattice, electronic entropies.
