| Abstract: | The magnetic properties of the spin-5/2 Blume-Capel model are investigated by means of the Mean-Field theory in a random single-ion anisotropy environment. The phase diagram is singled out as well as the thermal behaviors of the lattice magnetization. Numerical results reveal beyond first- and second-order phase transitions, the existence of isolated critical points. Novel magnetic orders are detected in the low-temperature range. Some thermal phase diagrams are constructed where the reentrant phenomenon often emerges. Interesting hysteresis loops are got when an external magnetic field constraint is imposed on the system. |
