Design, fabrication, and testing of sol-gel magnetic devices

Abstract

Sol-gel ferrite materials were fabricated for use in the core of a miniature bobbin-wound inductor. These materials were designed to improve the performance of an inductor at high frequencies. In particular, it should increase the inductance and Q value of inductors, keeping these values higher at frequencies in the kilo- and mega-hertz hertz ranges. This paper details the design, fabrication and test of these materials add devices. Problems are discussed and suggestions for improvements are given.
