Yttrium Ferrite (YFeO3) PLD Target

Introduction

Yttrium Ferrite is a complex oxide compound that exhibits interesting magnetic and optical properties, making it useful for a wide range of applications. In thin film form, Yttrium Ferrite has been extensively studied for its potential applications in spintronics, magneto-optics, and microwave devices. This material has a hexagonal crystal structure and is a member of the rare-earth iron garnet family.

Magnetic and Chemical Properties of Yttrium Ferrite

Yttrium Ferrite is a ferrimagnetic material with a high magnetic anisotropy and a Curie temperature of approximately 560°C. It has a high electrical resistivity and is chemically stable, making it suitable for various high-temperature applications.

Comparison with Similar Materials

Compared to other magnetic materials such as iron oxide and cobalt ferrite, Yttrium Ferrite has a higher magnetic anisotropy and a lower saturation magnetization. It also has a higher Curie temperature compared to other ferrimagnetic materials, making it suitable for high-temperature applications.

Crystal Structure of Yttrium Ferrite

Yttrium Ferrite has a cubic crystal structure with a lattice constant of approximately 12.4 Å. It consists of two interpenetrating sublattices, one of iron ions and the other of yttrium ions. The oxygen ions occupy tetrahedral and octahedral sites in the crystal lattice.

Typical Substrates for Epitaxial Growth

Yttrium Ferrite is commonly grown epitaxially on substrates such as gadolinium gallium garnet (GGG) and yttrium-stabilized zirconia (YSZ) due to their good lattice match and chemical compatibility.
