摘要
Within the framework of the model of interacting parameters of the magnetic and structural orders, taking into account the internal periodic magnetic field orthogonal to the exchange field, we analyzed the features of magnetostructural transitions in the Mn_{1-x}Co_{x}NiGe system. A qualitative description of changes in the nature of magnetic phase transitions from magnetostructural transitions of the 1st order paramagnetism-antiferromagnetism (x = 0.05-0.1) to isostructural transitions of the 2nd order paramagnetism-ferromagnetism (x = 0.15-0.8) with a change in the concentration of Co is presented. An explanation is given for the onset of irreversible magnetic-field-induced transitions at temperatures on the order of 5 K in strong magnetic fields, accompanied by a change in the saturation magnetization for samples x = 0.15-0.8. The low-temperature inverse magnetocaloric effect at liquid helium temperatures is predicted for these samples.
