Abstract
The Mössbauer spectra of La 2SrCu 1.95 57Fe 0.05O 6 were measured at various temperatures between 372 and 5 K. The spectrum measured at room temperature consists of two paramagnetic quadrupole doublets with similar Mössbauer parameters. The values of IS and small quadrupole splitting values indicate that high spin Fe 3+ 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 peaks of 520 and at 440 kOe. The magnetic susceptibility shows no distinct anomaly in this temperature range. Magnetic ordering seems to take place over a wide range of temperature.
