Abstract
The structural, magnetic, and transport properties of the polycrystalline-doped systems Nd0.7Sr0.3Mn1âxGaxO3 (0â¤xâ¤0.20) were investigated. For the parent and low-doped samples (0â¤xâ¤0.11), they show a long-range ferromagnetic state below TC and the Griffiths singularity above TC. 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 xc transforming from the Griffiths singularity to the cluster-spin-glass state.
