EXCHANGE INTEGRALS IN HG0.95MN0.05SE OBTAINED BY THE WAVE SHAPE-ANALYSIS OF SHUBNIKOV-DEHAAS OSCILLATIONS

The Shubnikov-de Haas oscillations were measured in Hg0.95Mn0.05Se at liquid helium temperatures, in magnetic fields up to 13 tesla. The ana lysis of the experimental data was performed by means of the wave shap e method. The dependence of effective g-factor of the conduction elect rons and difference Dingle temperature on magnetic field was determine d. Non-zero difference Dingle temperature is a clear evidence of spin dependent scattering in this material. The sp-d exchange constants con sistent with extracted spin splitting and difference Dingle temperatur e, alpha = -0.39 +/- 0.06 eV, beta = 0.95 +/- 0.07 eV, are in good agr eement with the values obtained from magnetooptics.
