Description
Summary:A systematic investigation of magnetic properties has been performed on intermetallic compound Pr2AgIn3, which crystallizes in a disordered hexagonal CaIn2-type structure. We present the experimental results of ac and dc susceptibility, magnetization, magnetic relaxation, specific heat and electrical resistivity measurements. The results provide clear evidence for the formation of spin-glass state in Pr2AgIn3 below a spin freezing temperature Tf∼3.7 K accompanied with a short-range magnetic order. The spin-glass behavior of Pr2AgIn2 is discussed and compared with that observed for the isostructural compounds Ce2AgIn3 and Nd2AgIn3 as well as other 2:1:3 spin-glass materials. The spin-glass state in Pr2AgIn3 can be considered to originate from the continued site randomness of the nonmagnetic elements, Ag and In, which introduce the random distribution of the RKKY interactions.
