Abstract
A systematic study on the structural, electrical and magnetic properti es of the ErFe4Ge2 intermetallic phase was carried out. From scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and high temperature electrical resistivity we found that the room temper ature ferromagnetism may be ascribed to the presence of an impurity of eutectic composition Fe:Ce=70:30. Low temperature electrical resistiv ity and magnetisation measurements showed three magnetic transitions a t 6.5, 21 and 40 K. (C) 1998 Elsevier Science S.A.
