Electronic transport and antiferromagnetism in the layered compoundBaCoS2

“…Bends in plots of (T), with values of the parameters comparable with those for BaCoS 2 at temperatures above and below the knee, have been reported for Se-deficient CdCr 2 Se 4 , which is a ferromagnet, 22 for highly oxidized perovskite SrFeO x which is an antiferromagnet, 23 for antiferromagnetic, nonstoichiometric or cation substituted ␣-MnS, 24 and for NiO ͑lightly doped with Li͒. 18 In the latter case, between 100 and 50 K the activation energy drops from 0.2-0.4 eV to 0.004 eV.…”

“…This material displays co-existence of long-range ferromagnetic ordering (with a T C 129.5 K) [19,20] and n-type semiconductivity [21,22]. Slight imbalance in the stoichiometry can lead to change in conductivity from n-type to p-type [23]. Large negative magnetoresistance and local lattice distortions were also reported in the ferromagnetic phase of this compound [24,25].…”

The effects of doping ferromagnetic spinel CdCr2Se4 with Sb3+ ions

“…close to the value expected for the magnetic moments carried by Cr 3 + ions. The electronic transport properties of CdCr 2 Se 4 strongly depend on the actual stoichiometry and the presence of lattice defects in the specimens studied [8][9][10][11]. For example, it was observed that selenium vacancies cause the electrical conductivity to change from n-to p-type [7,11].…”
