Colossal magnetoresistance in manganese oxides

摘要

At certain temperatures, nanoclusters form and improve the flow of electrical current through certain oxide materials, according to research carried out at the Brookhaven National Laboratory and the Universidad San Francisco de Quito. The findings could be employed in a number of industrial applications including spintronics. The unusually large variation in resistance to the flow of electricity in the presence of a magnetic field observed in some oxide materials is a phenomenon known as colossal magnetoresistance.
