Field-dependent magnetic circular dichroism (MCD) intensity curves (hysteresis cycles) are found to be essentially identical to superconducting quantum interference device magnetization results and provide experimental evidence for the potential of the optical technique for magnetic characterization. Optical observation of magnetic tunneling has been achieved by studying the decay of the MCD signal at weak applied magnetic field4 p.application/pdfeng(c) The American Physical Society, 2004Propietats magnètiquesPropietats òptiquesMatèria condensadaEfecte túnelDicroisme circularMagnetic propertiesOptical propertiesCondensed matterTunnel effectCircular dichroisminfo:eu-repo/semantics/article514644info:eu-repo/semantics/openAccess
