Hole Localization

Polycrystalline samples of Ru 1-x Sb x Sr 2 GdCuO 8 doped with Sb , in which magnetic order and superconductivity coexist with T magnetic ≫T c , were prepared by a solid state reaction technique. Lattice parameters, electrical resistivity, Hall and thermopower coefficients measurements on the same sintered ceramic samples are presented. Both Hall effect and thermopower show anomalous decreases below T magnetic which might be explained with a simple two-band model in the RuO 2 layer at T magnetic . It was also observed that the Sb doping reduce the conductivity of the system and the transition temperature decreases with increasing Sb content. This may be due to a distortion of RuO 6 octahedra which is responsible for the increase of hole localization.

The electrical resistivity ρ and the thermoelectric power S of Mn2−xCoxSb(x≦0.3) are studied. The abrupt change of ρ and S (0<x) appears near the temperature of magnetic order-order transition. S of Mn2–xCoxSb (0≦x≦0.3) is positive in the ferrimagnetic region and negative in the paramagnetic region. we have discussed these behaviour of ρ and S on the basis of the band structure of Mn2sb.

The electrical resistivity p and the thermoelectric power S of Mn3–xCoxGaC(x≤0.12) are studied to investigate the mechanism of the magnetic order-order transition. The ρ-T curves for samples with 0<x≤0.06 show the appearence of an intermediate magnetic phase. The experimental results suggest that the magnetic phase transitions of Mn3−xCoxGaC should be discussed in terms of itinerant electron magnetism.
