Abstract

We studied the magnetic transition of Mn1+ δAs1-xSbx after various heat treatments. It was found that quenching from a melted state and subsequent annealing give a sharp magnetic transition in the present system. The peaks of the magnetic entropy change, -ΔSM, in 0-5 T have almost the same high value of about 34 J/K kg for 0≤x≤0.3. The origin of large -ΔSM will be discussed from the thermodynamical point of view.
