Changes in the coercivity fields of magnetoresistance hysteresis loops under the influence of a spin-polarized current flowing through the half-metal CrO2 nanocomposite system

Abstract

Using the example of a pressed sample consisting of chromium dioxide nanoparticles coated with insulating shells, we study the relationship between the electron transport system and magnetic subsystem in granular spin-polarized metals. It is shown that the spin-polarized tunneling transport current can affect the coercivity fields of the percolation cluster formed in the sample with decreasing temperature.
