  The perovskite rare-earth (RE) chromite series (RE)CrO3 (RE = La, Ce, Pr, Nd,
Sm, Eu, Gd, Tb, Dy, Y, Ho, Er, Tm, Yb, Lu) has been synthesized in our
laboratory using microwave techniques. In this work we will demonstrate how
X-ray diffraction (XRD), Rietveld refinement of XRD pattern and complementary
High Resolution Transmission Electron Microscopy (HRTEM) were used to confirm
that the desired crystal structure had been formed. Field-emission scanning
electron microscopy (FE-SEM) gave clear indications of the shapes and sizes of
the powder crystallites. Magnetization measurement data was found to correlate
with the structural information obtained from XRD, Rietveld refinement and
HRTEM.
