Abstract

Each particle of modified chrome dioxide always contains the CrO2 compound or a solid solution on its basis, a nonmagnetic nucleus, and a surface oxide-hydroxide layer. The results of measurements of the magnetic properties of the CrxS1−x O2 (nanoparticle thickness of 40 nm) suggest that the character of sulfur distribution in particles changes upon heating and the properties of individual magnetic areas are nonadditively summed.
