Abstract
The dynamics of the magnetic properties of polycrystalline RuSr 2Ln1.5Ce0.5Cu2O10 (LnRu-1222, Ln=Gd, Y, Ho, Nd) have been studied by ac susceptibility. A frequency-dependent cusp was observed in χac vs. T measurements, which is interpreted as a spin-glass transition. These results are contrasted with the regular antiferromagnetic transition observed for YRu-1212.
