“…Rare-earth iron garnets are an important class of magneto-optical materials that are widely applied in photonics and spintronics for developing light modulators, circulators, , optical isolators, , magnetophotonic crystals, magnetic field sensors, , magnetic memory, magnetic data storage devices, and nonreciprocal elements of waveguide photonics . Among various garnets, Bi/YIG is one of the most extensively studied and widely used materials for the abovementioned applications due to a high magneto-optical figure of merit. , Conventional methods of Bi/YIG synthesis include liquid-phase epitaxy, , pulsed laser deposition, , sputtering, , sol–gel, and metal–organic decomposition (MOD) .…”

Femtosecond laser crystallization of magneto-optical bismuthsubstituted yttrium iron garnet (Bi/YIG) from an oxide film synthesized by the metal−organic decomposition method was demonstrated and studied. The maximum of the specific Faraday rotation of Bi/YIG films crystallized by laser pulses and that crystallized by conventional thermal annealing was shown to be 11 deg/μm at 515 nm for both types. In cases where Bi/YIG is a functional layer of a multilayered structure on a substrate, the proposed approach allows us to overcome limitations related to overheating of the structure and the substrate occurring during conventional high-temperature annealing.

Magnetoelectric effects in multiferroics give an opportunity to control intrinsic magnetic ordering with an external electric field. In this paper, we demonstrate the emergence of magnetic domains in the local electric field generated by cantilever tip in the (110)-oriented iron garnet film at room temperature. We show that the in-plane magnetized phase observed in this film enables the nucleation of the magnetic domain with 90°domain walls both at positively and negatively biased tip. The found bipolarity of the effect is in contrast to the unipolar nucleation of a bubble domain in the case of a conventional 180° domain wall. The experimental and theoretical studies reveal the mechanism of electric field generation of the 90° magnetic domain and its dependence on the domain wall's chirality.
