Heat capacity and magnetocaloric effect in polycrystalline and amorphous GdMn2

摘要: Abstract The Laves phases GdMn 2 has been recently prepared in amorphous structure. We present heat capacity measurements under magnetic fields up to 9 T both polycrystalline and states. No distinguishable anomaly at the order temperature is observed sample. In cases a very low field dependence of observed. calculated magnetocaloric effects give rise maximum centred 37 K crystalline form low, but broad 130 K
