Positive magnetoresistance in granular magnetic films with perpendicular anisotropy
What is it about?
Magnetoresistive properties of a granular film with the oriented uniaxial anisotropy of the granules has been studied experimentally and theoretically. Here we show, that the low-field part of the magnetoresistance curve slope can be transformed from negative to positive in the presence of ferromagnetic interparticle interaction.
