“…For x ≤ 0.035, a paramagnet to spin glass freezing was observed, while for x > 0.035 the transition was paramagnet–ferromagnet. [ 104 ] We believe that the low‐temperature spin glass state or ferromagnetic phase is related to the matrix, while the high‐temperature spin glass state is related to the Cr 5 Te 8 clusters.…”

Diluted magnetic semiconductors (DMS) are interesting because of the interplay between the electronic and magnetic subsystems. Selected magnetic properties of IV–VI DMS are described, looking at the similarities and differences between magnetic properties of II–VI, IV–VI, and III–V DMS. The influence of the crystalline and electronic structure of the material on its magnetic properties is focused on, especially on the exchange interactions among magnetic ions. Methods of determination of the exchange parameters are described by using different experimental techniques, such as measurements of magnetic susceptibility, magnetization, and specific heat. The development in the material technology from bulk crystals to thin films and nanostructures is followed.
