摘要：
The magnetocaloric effect (MCE) of NaFeO(2)nanoparticles has been investigated by phenomenological model (PM). The simulated temperature-dependent magnetization data are in good agreement with the experimental one. Based on PM, the MCE parameters obtained as results of simulation for temperature-dependent magnetization data. Furthermore, the simulation shows that NaFeO(2)nanoparticles have a prospective importance in magnetic refrigerants over a wide temperature range, including room temperature. This gives NaFeO(2)nanoparticles potentially practical for MR.
