    The addition of Cu, Ga, Mn, and Al completely eliminated the large hysteresis losses present in the undoped Gd5Ge2Si2 alloy between 270 and 330 K, broadened the magnetic entropy change delta peak, and shifted its peak value from 275 to 305K.

    Přidání Cu, Ga, Mn, a Al úplně eliminovalo velké hysterézní ztráty přítomné v čistých Gd5Ge2Si2 směsech mezi 275 a 305K, rozšířilo magnetickou entropickou změnu delta Sm anomalie a posunulo anomalii z 275 K na 305K.
