Air-stable organic-based semiconducting room temperature thin film magnet for spintronics applications

Abstract

Herein, we report on a preparation method of vanadium tetracyanoethylene, V (TCNE)x, an organic-based semiconducting room temperature thin film magnet. Previously, this compound has been reported to be extremely air sensitive but this preparation method leads to V (TCNE)x, which can retain its magnetic ordering at least several weeks in air. The electronic structure has been studied by photoelectron spectroscopy and the magnetic properties by superconducting quantum interference device. The properties mentioned above, in combination with complete spin polarization, makes this air-stable V (TCNE)x a very promising material for spintronic devices. © 2008 American Institute of Physics.
