SnTeおよびPbTeにおけるMn2+イオンの電子常磁性共鳴(IV)

The EPR studies have been reinvestigated on Mn ions in the Bridgemangrown SnTe and PbTe crystals over the temperature range 120 - 480 K. The Debye temperatures for both crystals were estimated from the temperature dependence of the hyperfine structure constant; approximately 200 K for SnTe and 110 K for PbTe. These values are comparable to the reported data. It was found that the g-value of SnTe was almost independent of temperature and Mn content studied. A numerical analysis of the observed EPR signals by taking account of the skin effect showed that the peak-to-peak linewidth reported previously was about 15-20% largerthan the estimated linewidth
