摘要

With the growing demand for low-temperature technologies, magnetic refrigeration, which is based on magnetocaloric effect (MCE) of magnetic materials, has attracted increasing attention. In this work, Li₉Fe₃(P₂O₇)₃(PO₄)₂ (LFPP) crystals have been grown by the high-temperature flux method. The crystal structural characterization is analyzed, and its magnetocaloric effect (MCE) is in detail investigated for the first time. The maximum magnetic entropy changes (−ΔS_M) of LFPP under a field change of 0–7 T are determined to be 4.6 J/kg·K (H⊥c) and 4.1 J/kg·K (H//c) at 4 K and 5 K, respectively. The slow decrease of −ΔS_M around the phase transition temperature implies that LFPP has a large refrigeration temperature range.
