Fabrication and ferromagnetic resonance study of epitaxial spinel ferrite films for microwave device applications Pachauri, Neha Date: Single crystalline nickel ferrite and lithium ferrite thin films have attracted a lot of research attention recently, because of their unique physical properties for practical applications in next generation technologies, such as monolithic microwave integrated circuits MMIC and multiferroic heterostructures.

The properties of these materials are closely related to the specific growth method and can be tailored by factors like surface morphology, microstructure and chemical composition. Different thin film growth techniques have been investigated in the past few decades for the fabrication of single crystalline thin films of both these spinel ferrites.

However, the difficulty to attain high quality, homogeneous epitaxial films with limited surface and bulk defects and low microwave loss still remains a challenging task.


Moreover, there have been very limited reports on the detailed ferromagnetic resonance FMR studies of these single crystalline nickel and lithium ferrite thin films, which is an essential aspect to understand the relaxation in magnetization precession microwave damping in these materials.

The growth conditions, which play a crucial role in attaining the desired film morphology and stoichiometry, are optimized to achieve epitaxial, single crystalline lithium ferrite films having low ferromagnetic resonance linewidth coupled with excellent magnetic properties.

The broadband frequency, angle and temperature dependent measurements reveal the existence of two-magnon scattering as the active relaxation mechanism for the films.Synthesis and Properties of Polymer Nanocomposites with Tunable Electromagnetic Response This Thesis is brought to you for free and open access by the Graduate School at Scholar Commons.

Spinel ferrites thesis

Spinel ferrites are magnetic semiconduc- tors with the general formula AB2O4, where A is a divalent metal ion and B is iron; however, iron can be partially substituted by other trivalent metal ions.
