Single crystals of Zn I _ xMnxCr204, where x = 0-1, were grown by the chemical vapour transport (CVT) technique using chlorine as the transport agent. A thermodynamic study of both systems, (ZnCr204 + MnCr204) CI2 and Znl_xMnxCrz04-CI 2, was done in order to investigate the effect of spurious species, i.e. MnCI2oin), on the transport of the mixed spinel, and structural investigations using X-ray diffraction were carried out. Susceptibility measurements as a function of temperature from 2-300 K for the different compositions are reported, and the magnetic phase diagram was determined as a function of composition and temperature.

Abstract
Single crystals of Zn I _ xMnxCr204, where x = 0-1, were grown by the chemical vapour transport (CVT) technique using chlorine as the transport agent. A thermodynamic study of both systems, (ZnCr204 + MnCr204) CI2 and Znl_xMnxCrz04-CI 2, was done in order to investigate the effect of spurious species, i.e. MnCI2oin), on the transport of the mixed spinel, and structural investigations using X-ray diffraction were carried out. Susceptibility measurements as a function of temperature from 2-300 K for the different compositions are reported, and the magnetic phase diagram was determined as a function of composition and temperature.File in questo prodotto:
