Abstract
Praseodymium (Pr)- and bismuth (Bi)-substituted yttrium (Y) iron (Fe) garnet (PrxY2-xBi1Fe5O12 where x =
0.25, 0.5, 1, and 2) thin films were prepared on glass substrate using a metal-organic decomposition (MOD)
method. Their magneto-optical properties were studied as a function of Pr concentration. Praseodymium has
two functions in PrxY2-xBi1Fe5O12 thin films, i.e., it (i) improves spin-orbit interaction strength and (ii) increases
magnetic properties; both are expected to strongly enhance the Faraday rotation (FR) angle of the thin film.
Our study demonstrated that the Pr1Y1Bi1Fe5O12 thin-film displayed the highest FR angle, of –13 °/μm, which
is 1.6-times higher than that of the PrxY2-xBi1Fe5O12 thin film without Pr dopant. The Pr1Bi1Y1Fe5O12 thin film
fabricated on a glass substrate by the MOD method displayed excellent MO performance and is a potential
candidate for application in optical devices.
