Magnetic circular dichroism in nanostructured hematite
Source abstract
Abstract
Abstract We have measured magnetic circular dichroism at room temperature in nanostructured hematite α -Fe 2 O 3 , which is antiferromagnetic in bulk. The dichroism was measured at the Fe L edge. Samples with very different colloidal sizes showed essentially equal dichroism signals. We conclude that the dichroism is originated at the core of the nanoparticles, as opposed to the net magnetic moment, which is believed to originate in the surface layer of the colloids.
