Abstract
Magnetic properties and magnetocaloric effects (MCE) of the tetragonal (ThCr2Si2-type) PrFe2Ge2 compound are investigated. The compound is determined to be antiferromagnet with the Néel temperature TN=14.5 K and undergoes a transition towards an incommensurate modulated structure at 7 K. A field-induced metamagnetic transition from antiferromagnetic (AFM) to ferromagnetic (FM) state occurs at 5 K under the critical magnetic field of 11 kOe. The maximum values of magnetic entropy change ( S) are –1.1 J/kg K and –6.3 J/kg K for the field changes of 0-20 kOe and 0-70 kOe, respectively. The large MCE with no hysteresis loss renders PrFe2Ge2 a competitive candidate for low temperature magnetic refrigerant.
