Magnetic properties of Sn/1-x/Cr/x/Te diluted magnetic semiconductors

, 2013
We present the studies of Sn/1-x/Cr/x/Te semimagnetic semiconductors with chemical composition x ranging from 0.004 to 0.012. The structural characterization indicates that even at low average Cr-content x < ?0.012, the aggregation into micrometer size ...
