We have investigated the magnetocaloric effect (MCE) of an Fe3GeTe2 single crystal near its Curie temperature (T-c) for magnetic field applying along the hard and easy magnetization directions. Magnetic susceptibility measurements indicate that it undergoes a ferromagnetic to paramagnetic phase transition around T-c similar to 200 K with high anisotropy. The maximum values of magnetic entropy change (Delta S-M) are estimated for magnetic field from 0-1 T to 0-7 T. Our main observation is that the Delta S-M along the easy axis is two to six times larger than that along the hard directions. We propose that magnetocrystalline anisotropy should be taken into consideration in order to maximize the performance of magnetic refrigerants.
