Abstract: We report a large entropy change DeltaS below 300 K, peaking near TC= 220K, due to isothermal change of magnetic field, for Gd4Co3, with a refrigerationcapacity higher than that of Gd. Notably, the isothermal magnetization isnonhysteretic - an important criterion for magnetic refrigeration without loss.DeltaS behavior is also compared with that of magnetoresistance.
