Electronic Properties and Magnetocaloric Effect of GdNi4Si: Ab Initio Calculations, Mean Field Approximation, and Monte Carlo Simulation

Theoretical analysis of magnetic properties and the magnetocaloric effect using the Blume-Capel model

“…Some models analyze the MCE using different methods. Recently, the properties of MCE were studied by several theoretical methods, namely, mean-field theory (MFT) [20][21][22][23][24][25][26][27], effective-field theory (EFT) [28][29][30][31][32][33], Monte Carlo (MC) simulation [34][35][36][37][38][39] and first-principles calculations [40][41][42].…”

Mean field theory and Monte Carlo simulation of phase transitions and magnetic properties of a tridimensional Fe7S8 compound

“…At the same time, the results of X-ray photoelectron spectrometry demonstrate that Fe 7 S 8 is composed of both Fe 2+ and Fe 3+ states [4]. In order to study theoretically magnetic properties and phase transitions of magnetic systems [15][16][17][18][19][20][21] many works have studied the mixed Ising model [22][23][24] by using different approximation methods like, Mean-Field Approximation (MFA) and Monte Carlo Simulation (MCS) [25][26][27][28][29]. In the present work, the structural, the electronic and the magnetic properties of Fe 7 S 8 compound have been studied.…”
