Abstrakt: A study is made of the thermal magnetic hysteresis of permanent magnets of the alloy YuNDK25BA in the residually magnetized state with different operating points after two cycles (+20° to 400° to 20°C) and (+20° to -195° to 20°C). The results are interpreted with the model developed earlier by the present authors for thermalhysteretic magnetization reversal in dispersion-hardened alloys. The results can be useful in evaluating the thermal stability of magnets and systems.
