- Аннотация: Light doping with copper (< 1 at.%)of the chalcogenide spinel CdCr2S4resulted in a strong rise (by about 90 deg.0 of the paramagnetic Curie point teta_p, compared with teta_p of the pure material. The ferromagnetic Curie point teta _f was not affected. This was attributed to the presence of giant magnetic quasimolecules formed around copper acceptor atoms. The electrical resistivity of the compound decreased strongly when the concentration of the dopant was increased: the addition of 1 at.% of copper reduced the resistivity by four orders of magnitude below the value for the pure material.
