Characterization of Bending Magnetostriction in Iron-Gallium Alloys for Nanowire Sensor Applications
… deposited nanowires of magnetostrictive iron-gallium (Galfenol) to mimic the sensing capabilities of biological cilia. Sensor design calls for incorporating Galfenol nanowires cantilevered from a membrane and attached to a conventional magnetic field sensor. As the wires deflect in …

Multiferroic Bismuth Ferrite-Lead Titanate and Iron-Gallium Crystalline Solutions: Structure-Property Investigations
Recently, multiferroics-defined as materials with coexistence of at least two of the ferroelectric, ferroelastic and ferromagnetic effects-have attracted enormous research activities. In this thesis, the structure and properties of multiferrioic BiFeO3-x%PbTiO3 and Fe-x%Ga crystalline solutions …

Iron-gallium alloys : temperature and field effects on [lambda]100 and magnetic anisotropy measurements
… temperature. Quenching to retain [alpha]-iron and B2 (CsCl) phases was found to increase magnetostriction, with the B2 structure creating the largest magnetostriction. The reasons for the atypical temperature dependence and the B2 structure enhancing magnetostriction are still unexplained. …

Framework for a Unified Macroscale Model of Magnetostriction
… the behavior of Terfenol-D while two different iron gallium alloys are modeled with varying accuracy. Next, this dissertation attempts to expand the 1D model to two dimensions. This requires numerical approximation techniques which take the form of quadrature methods in the existing …

CHARACTERIZATION AND MODELLING OF MAGNETO-AUXETICITY, THE MAGNETICALLY INDUCED AUXETIC BEHAVIOR, IN GALFENOL
Iron-Gallium alloy (Galfenol) is a magnetostrictive smart material (λsat ~400 ppm) with potential for robust transduction owing to good magneto-mechanical coupling and useful mechanical properties. In addition, Galfenol exhibits a highly negative Poisson’s ratio (denoted by ν) along the <110> …

Magnetoelectric Thin Film Heterostructures and Electric Field Manipulation of Magnetization
… were fabricated by depositing ferromagnetic iron-gallium (Fe-Ga) or cobalt ferrite (CoFe2o4 or CFO) films on top of differently-oriented ferroelectric PMN-PT substrates. Through significant electric field-induced strain in the piezoelectric substrate, the magnetic remanence and coercive …
