AbstractThe effect of the atomic disorder-order transformation on remanence enhancement and coercivity in isotropic CoPt magnets has been studied by isothermal annealing at 675degreesC, well below the transformation temperature, for 10-80 min after quenching in ice-water from 900degreesC. The results of X-ray diffraction, transmission electron microscopy, alternating-current (ac) susceptibility and magnetization measurements indicate that the strong remanence enhancement effect originates from exchange coupling between the face-centered-tetragonal (fet) ordered hard-magnetic precipitated phase and the face-centered-cubic (fec) disordered soft-magnetic matrix phase during the initial ordering transformation. The non-uniform distribution of the magnetic anisotropy results in a lower reversibility, unlike the so-called exchange spring magnet. (C) 2002 Elsevier Science B.V. All rights reserved.
