Abstract
The structural, magnetic, and transport properties of the polycrystalline-doped systems Nd0.7Sr0.3Mn1−xGaxO3 ( 0 ≤ x ≤ 0.20 ) were investigated. For the parent and low-doped samples ( 0 ≤ x ≤ 0.11 ), they show a long-range ferromagnetic state below T C and the Griffiths singularity above T C . When x further exceeds 0.12, a transition from the metal ferromagnetic to the insulating cluster-spin-glass state as a function of Ga doping takes places at low temperatures. x = 0.12 is just a critical point x c transforming from the Griffiths singularity to the cluster-spin-glass state.
