Growth of carbon substituted magnesium diboride Mg(B1-xCx)2 single crystals with 0<x<0.15 is reported and the structural, transport, and magnetization data are presented. The superconducting transition temperature decreases monotonically…

A heat capacity anomaly in the vicinity of magnetic transition was observed in single crystal GaFeO3 for the first time. The crystals grown along the expected electric polarization direction were characterized by X-ray diffraction,…

We have measured magnetization M(T,H), electrical resistivity ro(T,H), thermal conductivity k(T,H), and thermopower S(T,H) of polycrystalline samples of Nd1-xEuxNiO3; 0 <= x <= 0.35; as a function of temperature and external magnetic field.…
