Abstract
The heat capacity of the ferromagnetic shape memory effect alloy Ni2MnGa in submicrocrystalline and amorphous-nanocrystalline states has been measured in the temperature range 2 K ≤ T ≤ 310 K. Changes in the electron, magnetic, and lattice contributions to C P (T) as a result of megaplastic torsion deformation of samples under high pressure have been discussed.
