Magnetoresistance and Hall effect of chromium dioxide epitaxial thin films
Abstract
The CrO2 thin films epitaxially on TiO2(100) and Al2O3(0001) substrates were successively grown. The films have been structurally characterized using ex situ RHEED, X-ray diffraction and ion channeling spectroscopy. A Curie temperature of around 393 K is observed for the films, with those grown on TiO2 exhibiting a large magneto-crystalline anisotropy. Transport measurements show that films on TiO2 have a resistivity drop of about two orders upon cooling down from room temperature to 5 K.
