Evidence for a capacitor network near the metal insulator transition in VO2 thin films probed by in-plane impedance spectroscopy
J. -G. Ramírez, Edgar J. Patiño, Rainer Schmidt +3
Impedance spectroscopy measurements were performed in high quality Vanadium dioxide (VO2) thin films. This technique allows us investigate the resistive and capacitive contribution…
Signature of persistent metallic domains in FORC measurements of the VO metal-insulator transition
J. -G. Ramírez, A. Sharoni, Y. Dubi +2
We have performed first order reversal curve measurements of the temperature-driven metal-insulator transition in VO thin films, which enable quantitative analysis of the hyste…
Antiferromagnetism at the YBa2Cu3O7 / La2/3Ca1/3MnO3 interface
N. Haberkorn, J. Guimpel, M. Sirena +4
The magnetic properties of a series of YBa2Cu3O7-x/La2/3Ca1/3MnO3 (YBCO/LC1/3MO) superlattices grown by dc sputtering at high oxygen pressures (3.5 mbar) show the expected ferromag…
