Abstract
The Mossbauer spectra of (La2SrCu1.95Fe0.05O6)-Fe-57 were measured at various temperatures between 372 and 5 K. The spectrum measured at roo m temperature consists of two paramagnetic quadrupole doublets with si milar Mossbauer parameters. The values of IS and small quadrupole spli tting values indicate that high spin Fe3+ ions are in octahedral sites . The spectrum measured at 5 K consists of a broad sextet and a minor paramagnetic component. The distribution function of H(hf) shows two p eaks of 520 and at 440 kOe. The magnetic susceptibility shows no disti nct anomaly in this temperature range. Magnetic ordering seems to take place over a wide range of temperature.
