Thermo-reversible permanent magnets in the quasi-binary GdCo5-xCux system

Résumé

Ferrimagnetic GdCo5-xCux alloys exhibiting the effect of Gd- and 3d-sublattice magnetization compensation at defined temperatures were studied with respect to their use as thermo-reversible permanent magnets (PM). Coercive fields Μ0Hc in the range 0.3 to 1.6 T were measured for annealed single crystals with x = 1 – 2.2 having compensation points in the vicinity of room temperature. Two applications of such a thermo-reversible PM, namely a thermally controlled actuator and a contactless temperature sensor, are demonstrated.
