摘要: Relations between periods of spatially modulated first-kind antiferromagnetic structure and orthorhombic lattice distortion in an FCC are discussed on the basis Landau's phenomenological theory. The period modulation magnetisation is shown to be either same as or twice that distortion. On results, magnetic below Neel point gamma -Fe precipitated a Cu matrix, which was recently exhibit periodic distortion, discussed.
