摘要：

We report a large entropy change (ΔS) below 300K, peaking near T_C = 220K, due to isothermal change of magnetic field, for Gd₄Co₃, with a refrigeration capacity higher than that for, say, LaFe_11.4Si_1.6, ordering magnetically in the same temperature range. A noteworthy finding is that the isothermal magnetization is nonhysteretic – an important criterion for magnetic refrigeration without loss. ΔS behavior is also compared with that of magnetoresistance. <b>FullText for HTML: </b><a target="_blank" class="col_4A90E2" href="https://doi.org/10.1140/epjb/e2008-00266-x">https://doi.org/10.1140/epjb/e2008-00266-x</a>
