| contents | The exact recursion relations are used to study the mixed half-integer spin-(3/2, 7/2) Blume-Capel Ising ferrimagnetic system on the Bethe lattice. Ground-state phase diagrams are computed in the $({D_{A}}/{q|J|}, {D_{B}}/{q|J|})$ plane to reveal different possible ground states of the model. Using the thermal changes of the order-parameters, interesting temperature dependent phase diagrams are constructed in the ($D_{A}/|J|$, $kT/|J|$), ($D_{B}/|J|$, $kT/|J|$) planes as well as in the ($D/|J|$, $kT/|J|$) plane where $D=D_A=D_B$. It is revealed that the system exhibits first- and second-order phase transitions and compensation temperatures for specific model parameter values. Under the constraint of an external magnetic field, the model also produces multi-hysteresis behaviors as single, double and triple hysteresis cycles. Particularly, the impacts of the ferrimagnetic coupling $J$ on the remanent magnetization and the coercitive fields for selected values of the other physical parameters of the system are pointed out. Our numerical results are qualitatively consistent with those reported in the literature. |
