Abstract

The results of dc magnetization, ac susceptibility, magnetic relaxation, specific heat and electrical resistivity measurements on PrCoRuSi2, an amalgamation of the ferromagnetic compound PrRu2Si2 and the antiferromagnetic compound PrCo2Si2 crystallizing in the same tetragonal ThCr2Si2-type structure, are reported. The data for this sample reveal spin-glass-like anomalies at the temperature T0=15K where long-range magnetic ordering sets in. Below T 0, the observed irreversible magnetism, the long-time magnetic relaxation effect as well as the evident upward-shift of the peak temperature of ac susceptibility with increasing frequency are considered to originate, at least partly, from spin-glass-like magnetic frustration due to the competing magnetic interactions.
