Magneto-Optical Properties Of Co-Substituted Garnet Films Prepared By Pyrolisis Method

Ge was substituted in Co-substituted garnet film with no composition disparity to introduce Ge quadrivalent ions to compensate for the charges of the Co²⁺ ions. Co substitution increases the crystallization temperature while Ge substitution has the reverse effect. Faraday rotation coefficient measurements confirmed the existence of Co divalent ions in tetrahedral sites.
