Public award description

THE TEAM OF PRIME PHOTONICS, VIRGINIA TECH, AND UTRON KINETICS PROPOSE TO DEMONSTRATE A METHOD FOR FABRICATION OF A BULK, AMORPHOUS, COBALT-RICH MATERIAL THAT DEMONSTRATES LOW-NOISE MAGNETIC PROPERTIES, SUPERIOR TO THOSE OF THE 6-81.3 MO-PERMALLOY FAMILY. IN PARTICULAR, BULK COBALT-RICH AMORPHOUS MATERIALS WILL PROVIDE INCREASED PERMEABILITY, TUNABLE CURIE TEMPERATURE, HIGHLY CONTROLLED COERCIVITY AND SATURATION INDUCTANCE, ALL WITHOUT THE INTRODUCTION OF MAGNETOSTRICTIVE-BASED EXCESS NOISE. THE BULK NATURE OF THE MATERIAL WILL PROVIDE AN UNPRECEDENTED DEGREE OF FREEDOM IN CORE GEOMETRY DESIGN OVER EXISTING RIBBON-FORM AMORPHOUS ALLOYS, ALLOWING FOR NEAR-NET SHAPES OF DENSIFIED COMPACTS. THE COMBINED EFFECT OF THESE ENHCANCEMENTS WILL BE TO INCREASE FLUXGATE SENSITIVITY, DECREASE OFFSET AND NOISE, AND ALLOW FOR NEW, SMALLER GEOMETRIES IN FLUXGATE MAGNETOMETERS.
