Ferro-magnetic resonance (FMR) heating of magnetite powder compact and iron sheet

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

Among many recent projects on microwave processing in our group, selected recent challenges are presented in this paper. This is a new microwave heating method for processing of ferro (ferri)-magnetic materials, which takes advantage of FMR. Temperature increase of 200 deg. in iron sheet and 50deg. in Fe ₃O₄ compressed powder compact was observed by imposing the static external magnetic field (H^ext) perpendicular to the (separated) microwave magnetic (h) field. The temperature rise, the resonant magnetic field were investigated in various conditions. The heating mechanism or the dissipation of microwave energy converting to heat was briefly discussed.
