    We focus in this article on high field magnetoconductance results obtained on SnO2 polycrystalline (cassiterite) films. The high field magnetoconductance is found to be in agreement with the magnetoconductance universal behavior due to weak localization in two dimensions as suggested by Zduniak...

    We investigate transport through 6–10 nm thin epitaxial GaAs(001) barriers sandwiched between polycrystalline iron films. Apart from a pronounced tunneling magnetoresistance effect at low magnetic fields, we observe a distinct negative magnetoresistance (MR) at low and a positive MR at...

    We have investigated the correlation between magnetic and structural properties in exchange coupled polycrystalline CoO/Fe thin films. It has been found that an increase in interface roughness increases the exchange bias field as well as the coercivity. The magnetization reversal mechanism is...
