It has been shown that the spinel lattice greatly expands when its lattice parameter rises, which is caused by the substitution of Gd 3+ ions with larger ionic radii (= 0.938 Å) by the relatively smaller radius of the Fe 3+ … Ionic radius, rion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice. Ionic radii are typically given in units of either picometers (pm) or angstroms (Å), with 1 Å = 100 pm. Typical values range from 31 pm (0.3 Å) to over 200 pm (2 Å). home of hair altensteig
