Magnetocaloric response of FeCrB amorphous alloys: Predicting the magnetic entropy change from the Arrott–Noakes equation of state.
Description
The magnetic entropy change in Fe92−xCr8Bx x=12,15 amorphous alloys has been studied.
Increasing the B content, both the peak entropy change and the Curie temperature of the alloy
increase. This is in agreement with an increase in the average magnetic moment per iron atom. The
thermal and field dependences of the magnetic entropy change curves have been analyzed with the
use of the Arrott–Noakes equation of state. It is shown that determining the parameters in this
equation of state through fitting the magnetization data allows prediction of the field and
temperature dependences of the magnetic entropy change curves in a broad temperature range
around the Curie temperature.
