Abstract: We apply a recursion procedure to investigate the thermodynamic behavior and temperature dependence of magnetic entropy change (−ΔSm) of the recursive structure described by the Blume–Capel (BC) model with ferromagnetic interaction. Both order parameters undergo transitions from the ferromagnetic to the paramagnetic phase with continuous and abrupt discontinuities at finite temperatures. The results revealed significance of single-ion anisotropy, external magnetic field and lattice coordination in dominating various thermodynamic quantities such as susceptibility, specific heat, entropy and magnetocaloric effect. The Schottky-like anomaly appears when the low-temperature heat capacity reaches its maximum. The temperature dependency of magnetic entropy change has a clear minimum at low temperature. The magnetic entropy change can be improved by increasing the external magnetic field. Besides, the relative cooling power (RCP) increases linearly as the external magnetic field rises.
