The role of boron on the magneto-caloric effect of FeZrB metallic glasses
Fe-rich FeZrB metallic glasses exhibit magneto-caloric effect (MCE) around room temperature. Amorphous ribbons of two different compositions, Fe 91Zr 7B 2 and Fe 88Zr 8B 4, with respective Curie temperature values of 230 and 285 K have been studied. Although the maximum magnetic entropy change is re...
