Abstract:

The ac-susceptibility, magnetization, electrical resistivity and specific heat measurements have been performed to study the changes in the magnetic state and physical properties of the antiferromagnetic Gd3Co compound after rapid quenching from the liquid melt. It has been observed that the amorphization of Gd3Co modifies the magnetic state from antiferromagnetic to a soft-ferromagnetic like behavior, increases the magnetic ordering temperature (by about 30\%) and leads to substantial changes in the specific heat and electrical resistivity. A considerable enhancement of the exchange interactions in the rapidly solidified Gd3Co is ascribed to the appearance of a magnetic moment on Co atoms up to 1.6 mu(B). (C) 2015 Elsevier B.V.
