FIG. 1.

(a). Magnetization as a function of temperature for NdSrCo GaO (x = 0.0, 0.02, 0.03, 0.06, 0.08, 0.12) while cooling under a magnetic field of (a) H = 1 kOe and (b) H = 5 T. The inset of (a) shows the ferromagnetic Curie temperature (T) and ferromagnetic transition temperature (T*) as a function of composition (x). T* is the maximum in the field cooled temperature. (c) M versus H for all x at 10 K. (d) Coercivity (H) and spontaneous magnetization (M) as a function of Ga doping (x).

FIG. 2.

(a) Magnetization (M) as a function of temperature (T) for x = 0.12 sample under different magnetic fields. (b) M-H isotherms at different temperatures, (c) coercivity (H), and spontaneous magnetization (M) as a function of different temperatures.

FIG. 3.

(a) Resistivity (ρ) as a function of temperature (T) for NdSrCoGaO (x = 0.0, 0.02, 0.03, 0.06, 0.08, 0.12), (b) ρ(T) at H = 0 and 5 T for x = 0 and 0.02, (c) magnetoresistance for H = 5 T for all the compositions, (d) field dependences of magnetoresistance and magnetization at 10 K for x = 0.12 sample.

FIG. 4.

(a) Resistivity (ρ) as function of square of temperature (T) for low temperature for NdSrCoO. (b) lnρ versus (T) for low temperature for doped sample (x = 0.02, 0.03, 0.06, 0.08, 0.12).
