X-ray diffraction pattern of samples.
Temperature dependence of (a) resistivity and (b) magnetization for samples; the temperature of MI transition is marked with the signal ↑.
Temperature dependence of the inverse susceptibility for all doped samples (the signal ↓ and the straight lines denote the Griffiths temperature and the fitting curve with the Curie-Weiss law, respectively).
Electronic spin resonance spectra of samples at different temperatures (the signal ↑ denotes the FM resonance peak); the inset is the temperature dependence of .
