Abstract
We report the results of ac and dc magnetic susceptibility (χ), heat-capacity (C), isothermal magnetization, and isothermal remanent magnetization measurements on the compound Sr3CuRhO6 crystallizing in a K4CdCl6-derived monoclinic structure. The magnetization data reveal distinct magnetic anomalies near 6 and 12 K with decreasing temperature (T). While the transition below (T0=) 6 K appears to be of a spin-glass type as inferred from all the data, the one at 12 K is not typical of bulk ferromagnetism, in contrast to an earlier proposal. In the range of 6-12 K, the dc χ obeys the form χ−1α(T-T0)1−λ (0<λ<1) for very low dc fields, and the values of χ decrease gradually with the application of higher magnetic fields, mimicking the behavior of Griffiths phases.
