Some Factors Affecting on Magnetic Characteristic Quantities and Tc Curie Phase Transition Temperature of the Ni Nanoparticles by the Classical Heisenberg Model

Abstract

This paper investigates the effect of particle size D = 4.51nm, 5.03nm, 5.42nm, 5.91nm, rate of heat 4.1012K/s, 4.1013K/s, 4.1014K/s on magnetic characteristic quantities: Magnetization M, specific heat Cv, energy E, magnetic susceptibility c and Tc Curie phase transition temperature by classical Heisenberg model. The results show when increasing D particle size then Tc Curie transition temperature increases and when increasing rate of heat then Tc decreasing. In addition, there is the influence of D size and heating rate on magnetic characteristic quantities.
