Magnetocaloric properties of the spin-S (S ≥ 1) Ising model on a honeycomb lattice
چکیده انگلیسی
Using effective field theory, we have investigated magnetocaloric features of the spin-S Ising model for some spin values S=1,3/2,2,5/2,3 and 7/2 on a honeycomb lattice. Effects of the external magnetic field on the isothermal entropy change, its half-width and also cooling capacity have been determined and discussed in detail. The numerical results show that the isothermal entropy change decreases whereas its half-width and cooling capacity tends to increase when the spin magnitude of the system is increased starting from S=1 to 7/2 for a fixed value of the external field. Finally, we have also performed some calculations to check the applicability of magnetocaloric scaling procedure for the present system. It is found that the rescaled numerical data collapse onto the same universal curve for all considered values of spin component S.
