Magnetic field effects during deposition on crystal structure and magnetic properties of BaFe12O19 thin films prepared using PLD in the magnetic field (dynamic aurora PLD)

Abstract

Epitaxial barium hexaferrite [BaFe12O19 (BaM)] thin films were grown on YSZ-buffered Si(001) substrates using a PLD apparatus in which an electromagnet had been installed (dynamic aurora PLD). We examined the effects of applying a magnetic field (up to 2 kG) on the crystal structure and magnetic properties during deposition. The application of the magnetic field during deposition had little effect on the orientation, residual strain, and Curie temperature of BaM thin films. However, the crystallinity and saturation magnetization of the films were lowered. Possible reasons for the lowering of saturation magnetization are discussed. © 2013 The Ceramic Society of Japan.
