摘要
The magnetocaloric effect of Fe91-xMo8Cu1Bx (x=15,17,20) amorphous alloys has been studied. The temperature of the peak of magnetic entropy change can be tuned by altering the Fe/B ratio in the alloy, without changing its magnitude, parallel to Delta S-M(pk)parallel to. The average contribution of the Fe atoms to parallel to Delta S-M(pk)parallel to increases with increasing B content. This is correlated with the increase in the low temperature mean magnetic moment of Fe. A recently proposed master curve behavior for the magnetic entropy change is also followed by these alloys and is common for all of them.
