摘要：

The magnetic properties of 10 nm size Ni(OH)(2) nanoparticles prepared by sol-gel method have been studied. The magnetic moments increase with decreasing temperature in a low applied field, which is due to the spin-frozen-like state at low temperatures, and the metamagnetic transition is not clearly observed even in an applied field of 70 kOe due to the size effect. Furthermore, the transition from paramagnetic to antiferromagnetic in the Ni(OH)(2) nanoparticles occurs at lower temperature (22 K). (C) 2010 American Institute of Physics. [doi:10.1063/1.3374468]
