FIG. 1.

XRD patterns of (, 0.1, 0.2, 0.3, and 0.4) samples synthesized by solid state reaction. All the peaks were indexed with JCPDS Card No. 47–0069.

FIG. 2.

Raman spectra of collected at room temperature: (a) Raman spectra for samples with to 0.4. (b) Normalized Raman spectra with fitted Raman peaks for undoped specimen. The vibration modes are indexed.

FIG. 3.

Field cooled magnetic susceptibility as a function of temperature for the (, 0.1, 0.2, 0.3, and 0.4) samples in a magnetic field of 1000 Oe over the temperature range from 10 to 700 K. Inset (a) shows curves measured from 2 to 100 K, in which decreases with increasing doping level (with indicated by the corresponding arrows). Inset (b) shows curves measured in the high temperature range.

FIG. 4.

Inverse magnetic susceptibility as a function of temperature and the Curie–Weiss law fittings are shown above from 600 to 700 K for each sample.
