Sc(Fe1 xNix)2 - Opis:
- The structural and microscopic magnetic properties of the pseudobinary Sc(Fe1 xNix)2 system were studied by XRD and Mössbauer measurements in the range of 0.10 less-than or equal to - x less-than or equal to - 0.60. All investigated samples have the cubic C15-type structure. Both the magnetic hyperfine field on 57Fe and the Curie temperature decrease with increasing Ni content and the system becomes paramagnetic for x H 0.60 at room temperature. The form and temperature dependences of the Mössbauer spectra for 0.40 less-than or equal to - x less-than or equal to - 0.50 indicate the coexistence of paramagnetic and ferromagnetic regions in the samples and occurrence of magnetic clusters with a wide distribution of the Curie temperatures. As follows from the near to zero values of quadrupole shifts in Mössbauer spectra it results that a <100> direction is a local easy magnetization axis for x e 0.10.
