Effect of the ionic radius on structural properties of orthochromites RCrO3 (R = La, Gd, Y)

The main objective of this work was to detail out how to obtain important parameters in the structural analysis of materials with perovskite structure in order to help beginning researchers in this area. In particular, a thorough comparative and investigative study of the effect of ionic radius on t...
