Magnetic Susceptibility of NiO Nanoparticles
S. D. Tiwari, K. P. Rajeev
Abstract
Nickel oxide nanoparticles of different sizes are prepared and characterized by x-ray diffraction and transmission electron microscopy. A.C. susceptibility measurements as a function of temperature are carried out for various particle sizes and frequencies. We find that the behavior of the system is spin glass like.
