Abstract

In the present report, an unusual observation of Griffiths phase-like magnetic behavior in a geometrically frustrated antiferromagnetic system, Sr2InRuO6, has been discussed. This surprising magnetic behavior in the present sample is found to be associated with the presence of clusters above and below the critical temperature (Tcr � 150 K). Two plausible scenarios are discussed for this intriguing observation of nonanalytical inverse susceptibility in this system. These scenarios are based on significant changes in the saturation magnetization of the clusters and changing concentrations of the clusters with decreasing temperatures. The average size of the clusters was estimated to be �4.9 nm at 300 K and �2.7 nm at 100 K. A �17-fold increase in the cluster concentration across Tcr � 150 K results in non-analytical behavior of inverse susceptibility observed in this system. Additionally, the electrical properties of Sr2InRuO6 are reported. © 2024 The Royal Society of Chemistry.
