Curie temperatures and critical exponent properties of FePd ferromagnetic materials by data simulations approach

Abstract

This paper has systematically investigated the Curie temperature of Fe_1-xPd_x ferromagnetic materials under the data simulations approach. Using a Monte Carlo model, we calculated the Curie temperatures of Fe_1-xPd_x. The Curie temperature of the nanomaterial Fe_1-xPd_x was measured on variation of compositions (x) at x = 0.1, 0.3, 0.5, 0.7, and 0.9. The Curie temperature of nanomaterial Fe_1-xPd_x was found decreasing when the palladium (Pd) composition was increased. The Curie temperature is the transition temperature of ferromagnetic to a paramagnetic phase which can be analyzed using the calculation of critical exponents. The Curie temperature of data simulations was obtained and compared to the calculation of critical exponents. The results showed no difference of the Curie temperature obtained from both approaches.
