Theoretical Investigation of Both Size and Shape Effects on
Ferromagnetic Nanocrystals Curie Temperature

Department of physics, PayameNoor University, Golestan Town, Shiraz
Abstract
In this paper we study about both size and shape effects on the Transition temperature of
ferromagnetic nanocrystals for the first time. Also a thermodynamic approach is proposed
to the mechanism of size and shape dependent of ferromagnetic transition temperature.
One relation that is obtained, is a simple and unified function without any adjustable
parameter that pre-established for the size dependent of ferromagnetic. Also to find of
shape effects on the Curie temperature of ferromagnetic nanoparticles a model was
developed, that is based on the relation cohesive energy and temperature variations.
Keywords: Nanoparticles, Ferromagnetic, Curie Temperature, Transition, Temperature.
