Ultra-fast spectroscopy investigation of Verwey transition in magnetite

Ultra-fast spectroscopy investigation of Verwey transition in magnetite

Magnetite has a different electrical resistance behavior with temperatures below and above the Verwey temperature. Here, we report on Verwey transition in Fe3O4 by means of the frequency-doubled output from the Ti-sapphire laser in pump-probe experiments and from the insulator to metal transition ob...

We observed a clear difference below and above the Verwey temperature in ultra-fast transmission changes.http://ijpr.iut.ac.ir/browse.php?a_code=A-10-1-736&slc_lang=en&sid=1Verwey transition magnetite metal-insulation transition pump-probe
