Critical behaviour and magnetic interactions in the diluted systems ZnxHg1−xCr2Se4 (0⩽x⩽1)

ESR study of new layered semiconductor Ga2Cr1.33Se5

“…It was shown that replacement of the di-or trivalent cation by a third metal resulted in new chemical compounds with essentially changed properties interesting for both basic research and technological aspects [10][11][12][13][14][15]. Quaternary selenides, crystallising with the spinel-type structure, can usually be obtained in a whole concentration range of the dopant [16][17][18][19][20][21], while those with a non-spinel structure show a limited solubility and often the end-member of the system remains unknown [21][22][23].…”
