摘要: The anisotropic paramagnetism and specific heat in Nd2Ti2O7 single crystals are investigated. angular dependence of the magnetization Weiss temperatures show dominant role crystal field effect magnetization. By incorporating results from diluted samples, contributions to temperature exchange interactions isolated. found be ferromagnetic, while contributes a large negative part temperature, along all three crystallographic directions. under magnetic reveals two-level Schottky ground state scheme, due Zeeman splitting doublet, g-factors thus determined. These observations provide solid foundations for further investigations Nd2Ti2O7.
