Abstract
In this Study, Qi model, Jiang model and Lu model, are used to predict the variation of magnetic properties with size and shape in nanosolids. Magnetic properties of nanosolids such as Curie Temperature (Tcn), Magnetization (Msn) and Neel Temperature (Tnn) of Cu, Ag are studied. It is predicted that as the size of nanosolids is decreased, all these three properties decrease with decreasing size. These magnetic properties are also studied with different shapes of nanosolids, such as thin films, cylindrical nanowires, spherical, regular tetrahedral nanoparticles and regular triangular cross-section nanowires. The computational results are compared with the available experimental and simulated data to validate our theory.
