NiTex nanorods (x=1.00, 1.15, 1.33, 1.60, 1.80, 2.00) with average diameter of 150nm have been selectively synthesized by a simple hydrothermal process. The nanorods with various x share similar hexagonal structure and morphology. NiTe nanorods present paramagnetic property at both high and low temperature while NiTe2 nanorods exhibit a diamagnetic characteristic at high temperature and a paramagnetic behavior below 58K. The magnetic moment reduces with the increase in tellurium content. The difference in magnetic behaviors of NiTex nanorods is mainly attributed to the competition between the diamagnetism and paramagnetism based on the experimental observation.
