Phys. Rev. B 71, 014422 (2005) [6 pages]Ground state splitting for the Mn2+ ion in PbMnTe compoundsReceived 14 November 2003; revised 27 July 2004; published 14 January 2005 We propose a new mechanism leading to the ground state splitting for the Mn2+ ion in PbMnTe crystals. The splitting is due to two effects, one of which is the hybridization of 3d electrons with the band states and the other is the internal spin orbit interaction in Mn1+ and Mn3+ states of the manganese ion. We also study the effect of a local crystalline distortion on the character and magnitude of the splitting. The theoretical predictions are compared to experimental results. © 2005 The American Physical Society URL:
