Origin of satellite structures of high field epr in Cd1−xMnxTe

The electron paramagnetic resonance (EPR) of Mn²⁺ in Cd_1?x Mn _x Te was examined at low temperatures and high magnetic fields with the Mn concentration ranging fromx=0.01 tox=0.65. A far infrared laser was used as a radiation source. The structure of the resonance is strongly influenced by electromagnetic propagation effects. By variation of the sample thickness it was clearly shown that the satellite structures besides the main EPR peak, formerly explained as originating from transitions in the Mn²⁺ pair energy level scheme, are solely due to interference effects.
