Griffiths phase and critical behavior in layered Sr\(_2\)IrO\(_4\) ferromagnet

We report the existence of Griffiths phase (GP) and its influence on critical phenomena in layered Sr\(_2\)IrO\(_4\) ferromagnet (T\(_C\) = 221.5 K). The power law behavior of inverse magentic susceptibility, 1/\(\chi\)(T) with exponent \(\lambda = 0.18(2)\) confirm the GP in the regime T\(_C\) \(
