    Spin-lattice coupling in the ferrimagnetic semiconductor FeCr2S4 probed by surface acoustic waves

    Full text link
    Using surface acoustic waves, the elastomagnetic coupling could be studied in thin single crystalline plates of the ferrimagnetic semiconductor FeCr2S4 by measuring the attenuation and the frequency tracking in the temperature range 4.2 K to 200 K. The data clearly display the anomalies found in low-field magnetization measurements.Comment: 15 pages, 3 figures. To appear in J. Appl. Phys., 99 (2006

    Neutron diffraction study of the spinel FeCr2S4 shows the degree of inversion to be zero and the sulphur parameter to be u = 0,2608. Low temperature results agree with a simple ferrimagnetic model.L'étude par diffraction de neutrons du spinelle FeCrS4 montre que le degré d'inversion est nul et que le paramètre du soufre est de u = 0,2608. L'étude à basse température a confirmé l'existence d'un ferrimagnétisme simple
