dc.description.abstract Nickel copper ferromanganites Cu1-xNi xFeMnO4 with the composition (0≤x≤1) have been prepared using a ceramic technique. A single phase of these compounds was confirmed by X-ray powder diffraction measurements. Mössbauer spectra were recorded in 20-628 K temperature range. The spectra of all samples showed two well-resolved Zeeman patterns corresponding to A- and B-sites. At room temperature the hyperfine field increases with decreasing Cu concentration. The cation distribution obtained from analysis of Mössbauer spectra revealed a partially inverse spinel structure. The Curie temperature (TC) increased with the increase of the composition parameters (x). The specific heat Cp for nucleus 57Fe was calculated from Mössbauer data for Cu0.5Ni0.5FeMnO4, and NiFeMnO 4. The temperature dependence of the hyperfine parameters was studied, for these samples. The sublattice magnetization H(T) obeys the one-third power law in the range 0.47<T/TC<0.92. © 2004 Elsevier B.V. All rights reserved.
