In this study, we investigated the magnetic ordering and underlying mechanism of the Griffiths phase, observed
in Ho2NiMnO6 through AC susceptibility measurements. Our results indicate that the transition around 86
K corresponds to a paramagnetic to ferromagnetic transition characterized by classical magnetic ordering.
Notably, nonlinear AC susceptibility measurements revealed the existence of ferromagnetic clusters within a
paramagnetic background well above the transition temperature, establishing this as the origin of the Griffithslike phase within the Ni/Mn sublattice of Ho2NiMnO6. Our study on the Ho2NiMnO6 system provides insight
into the intricate magnetic phenomena common to various other strongly correlated electron systems.
