O tratamento pós-recozimento para filmes finos magnéticos de CoCrPt foi testado em diferentes condições térmicas, alterando o tempo do procedimento de recozimento. Coercividade (Hc) a melhoria foi alcançada na amostra recozida em comparação com aquelas depositadas, nas quais foram alcançados até 5.2 kOe. Para esclarecer o mecanismo de tratamento de recozimento nas propriedades magnéticas, os espectros de difração de raios X (XRD) dessas amostras e suas propriedades magnéticas foram cuidadosamente estudados. Os parâmetros da rede Co e Cr foram calculados separadamente a partir de diferentes planos da rede cristalina. Verificou-se que o espaçamento da rede do eixo da estrutura hexagonal Co aumenta monotonicamente com o aumento do tempo de recozimento. Variação de Co profissional de saúde A significância dos picos pode ser devida à redistribuição de Cr ou Pt nos grãos de cristal e seus limites. Combinado com a análise do tamanho de grão da área rica em Co por largura de alargamento do pico de difração de raios X, que não foi muito consistente com o resultado obtido em outros estudos de TEM e AFM, a difusão de Cr foi sugerida como o fator governante na região de tempo de recozimento curto . O crescimento de grãos co-ricos também deve ser aplicado para explicar a variação das propriedades magnéticas em pós-recozimento mais longos.

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.
