| 中文摘要 | Magnetic properties and magnetocaloric effects (MCEs) of the antiferromagnetic (AFM) ErTiSi compound with a Neel temperature T(N)=46 K are studied by magnetization measurements. Two successive magnetic transitions in the thermomagnetic M-T curves, an AFM-AFM transition followed by an AFM-paramagnetic transition with increasing temperature, are observed. ErTiSi undergoes a field-induced metamagnetic transition from AFM to FM state below T(N). A sign change in MCE with increasing temperature or magnetic field in ErTiSi is observed near the critical field. The maximal value of magnetic entropy change Delta S(m) is -8.9 J/kg K around T(N) for a field change of 0-5 T. The modest Delta S(m) as well as no hysteresis loss around T(N) in ErTiSi may be useful for its application in magnetic refrigeration. (C) 2010 American Institute of Physics.
