摘要：
CoNi alloy nanoparticles were prepared via a solvothermal method, and ethanol and water mixed solution was used as solvent. No surfactant or template was employed during the entirely synthetic procedure. The dependences of product size and shape on the temperature and volume ratio of ethanol to water were investigated in details. As the volume ratio of ethanol to water decreased, the shape of CoNi alloy changes from particle to platelets. The obtained samples were characterized by XRD, SEM, and VSM techniques. Magnetic measurement at room temperature showed that the CoNi nanoparticles possessed ferromagnetic behavior, and these CoNi nanoparticles could be used in magnetic media, sensors, and other devices.
