Abstract—
The isobaric temperature dependences of the magnetization and the magnetocaloric characteristics of alloys of the Mn1 – xCrxNiGe system are studied in a constant magnetic field up to 10 kOe in the range of hydrostatic pressures up to 12 kbar. It has been established that, with increasing pressure, the implementation of helimagnetic ordering undergoes qualitative changes from smooth hysteresis-free 2nd order phase transition to 1st order phase transitions, accompanied by the appearance of a temperature hysteresis and an increase in the magnetocaloric effect. Based on the exchange-structural model, an explanation is given for the mechanism of baric transformation of magnetic and magnetocaloric properties.
