The effect of Cu on the magnetic properties of slowly cooled bulk amorphous alloys has been studied by room-temperature magnetic measurements. Ferromagnetic bulk amorphous cylinders of 3 mm diameter and 50 mm in length with a coercivity of 298 were obtained by copper mold casting. The addition of 1 at. % Cu into the alloy causes an increase in coercivity to 321 Further addition of Cu by replacing neodymium, however, results in an abrupt decrease in coercivity to 41 for alloys with due to the precipitation of a Fe-rich magnetically soft phase. The improvement of the hard magnetic properties by the addition of 1 at. % Cu for the cast based bulk amorphous alloys may be attributed to an enhanced clustering of Nd–(Fe, Co) pairs in the amorphous alloys.
