Scientists enhance synthesis of chromium dioxide (100) epitaxial thin film growth

8 agosto 2014

High quality CrO2 film on the (100)-oriented TiO2 substrate was fabricated by using a simple route under ambient pressures. The film shows preferential orientation along (100) direction and has a Curie temperature Tc = 396 K. The resistivity of the film is studied down to about 0.6 K and can be fitted with Á(T)=Á0+AT2exp(-”/T). The magnetization of the film becomes saturated in a relatively low field and follows Bloch’s T3/2 law.
