摘要	The magnetic phase transition and magnetocaloric effect are investigated on epsilon-(Mn0.83Fe0.17)(3.25)Ge compound. A large positive magnetic entropy change Delta S-M is observed, which is accompanied with a field-induced metamagnetic transition from a collinear to a triangular antiferromagnetic configuration in this antiferromagnetic compound. The maximum value of Delta S-M is 11.6 J/kg K at 93 K for a magnetic field change of 7 T. The study on systems with antiferromagnetic phases may open an important field in searching new materials for magnetic refrigeration. (c) 2007 American Institute of Physics.
