Des traitements post-recuit pour des couches minces magnétiques de CoCrPt ont été essayés dans différentes conditions thermiques, en modifiant la durée de la procédure de recuit. Coercivité (Hc) une amélioration a été obtenue dans les échantillons recuits par rapport à ceux tels que déposés, dans lesquels une valeur aussi élevée que 5.2 kOe a été atteinte. Pour clarifier le mécanisme du traitement de recuit sur les propriétés magnétiques, les spectres de diffraction des rayons X (DRX) de ces échantillons et leurs propriétés magnétiques ont été soigneusement étudiés. Les paramètres de réseau Co et Cr ont été calculés séparément à partir de différents plans de réseau cristallin. Il a été constaté que l’espacement du réseau d’axes de la structure hexagonale de Co augmente de manière monotone avec l’augmentation du temps de recuit. Variation de Co hcp L'importance des pics peut être due à la redistribution du Cr ou du Pt dans les grains cristallins et leurs limites. Combinée à l'analyse de la taille des grains de la zone riche en Co par diffraction des rayons X, qui n'était pas très cohérente avec les résultats obtenus dans d'autres études TEM et AFM, il a été suggéré que la diffusion du Cr était le facteur déterminant dans une région de temps de recuit courte. . La croissance des grains riches en co devrait également être appliquée pour expliquer la variation des propriétés magnétiques au cours d'un recuit plus long.

Abstract: Post annealing treatment for CoCrPt magnetic thin films were tried in different thermal conditions, by changing the time of annealing procedure. Coercivity (Hc) improvement was achieved in annealed sample compared with those as deposited, in which as high as 5.2 kOe has been attained. To clarify the mechanism of annealing treatment on the magnetic properties, X-ray diffraction (XRD) spectrums of those samples and their magnetic properties were carefully studied. Co and Cr lattice parameters were separately calculated from different crystal lattice plane. It was found that a axis lattice spacing of Co hexagonal structure increases monotonically with increased annealing time. Variation of Co hcp peaks significance may due to Cr or Pt redistribution in the crystal grains and its boundaries. Combined with the grain size analysis of Co-rich area by X-ray diffraction peak broaden width, which was not very consistent with the result obtained from other's TEM and AFM studies, Cr diffusion was suggested to be the governing factor at short annealing time region. Co-rich grain growth should also be applied to explain the variation of magnetic properties in longer post annealing.
