Abstract

The Ca3(Nb,Ga)5012 single crystals with the 1,2509 nm lattice parameter and low absorption in visible and near infrared wavelength range have been grown by the Czochralski technique from a platinum crucible. The growth temperature was about 1430°C. The growth conditions for liquid phase epitaxy of the iron garnet films on the new Ca3(Nb,Ga)5O12 substrates have been investigates using the Pb0-Bi2O3-B2O3 flux system. The general composition garnet films (Y,Lu,Bi)(Fe Ga)5O12 were grown on (110)-oriented substrates. The horizontal modes of diping were used for the film growth. The Bi content in the prepared films was more than 2,0 atoms per formula unit. The present paper reports the film quality, the interface (substrate/layer) properties, as will as the magnetic and magneto-optical properties of these layers. The information about the interface (substrate /layer) was obtained using the results of study of pulsed film remagnetization. The dynamics of magnetic domain walls was studied usins a high photography method.
