Relations between the phase transformation yields, the hystereses and the extents of transformation in magnetic shape memory alloys

The Clausius-Clapeyron relation, which is introduced in the case of multi-axial thermo-magneto-mechanical loadings, shows an additive effect between Magnetism and Mechanics on the shift of transformation temperatures. For linear dependence of these temperatures, it permits to link, firstly, the phase transformation Yields on stress and on magnetic field (or the critical stress and the threshold magnetic field), secondly, the hystereses and, thirdly, the extents of temperature during transformation in magnetic shape memory alloys, such as, NiCoMnIn.
