Abstract
The compounds, NiSb2O6(NSO) and MnSb2O6(MSO) attract the community for the quasi one-dimensional and layered structure composed of Ni2+and Mn2+, which orders antiferromagnetically atTN= 6.7 and 12 K, respectively. Here, we report the Griffiths-like phase much aboveTNin the range of 37-85 K and 25-80 K for NSO and MSO, respectively. The dc magnetization results indicate the Griffiths-like phase, following the modified Curie-Weiss law. The magneto-capacitive responses for both the compounds show anomalies at the onset of the Griffiths-like phase. Intriguingly, the low temperature synchrotron diffraction results are conclusive for determining the singularities for both the compounds. Interplay between the low-dimensionality, magnetic frustration, and magneto-elastic coupling correlates the observed short range ordered state, which is suggested as a Griffiths-like phase, aboveTNfor both the compounds.
