Monte Carlo Study of Magnetic Properties and Magnetocaloric Effect of a Nano Square-Hexagon «4-6» Structure with Half-Integer and Integer Mixed Spins.

In this work, we study the magnetocaloric properties of half 5/2 and integer 3 mixed spin model on a square–hexagon «4-6» structures are studied by Monte Carlo simulations. The total magnetization and the magnetization of each sub-lattice of the mixed-spin lattice have been analyzed. The magnetic susceptibility, dM/dT and magnetic entropy changes are found. The magnetic hysteresis cycles under, with the temperatures, exchange interactions (S-S), (σ-σ) and (σ-S), and the crystal fields (Dσ and DS) has been discussed. [ABSTRACT FROM AUTHOR]
