MBE Deposition of Epitaxial Fe1-xVx Films for Low-Loss Ghz Devices; Atomic-Scale Engineering of Magnetic Dynamics

Abstract

Public Reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. AbstractWe report on the deposition of epitaxial iron and iron alloy thin films with the lowest GHz linewidths ever attained in metallic ferromagnets. Maximum halfpower Q is shown of 100 at 10 Ghz and 140 at 40 Ghz, significantly higher than known previously for metals.
