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 (-Delta SM) of LFPP under a field change of 0-7 T are determined to be 4.6 J/ kg center dot K (H perpendicular to c) and 4.1 J/kg center dot K (H//c) at 4 K and 5 K, respectively. The slow decrease of-Delta SM around the phase transition temperature implies that LFPP has a large refrigeration temperature range.
