Paper Abstract

Work is described on the development of a £canned Near-field Qptical Microscope (SNOM) to observe magnetization distributions with sub-wavelength resolution. Contrast is provided by the magneto-optic Kerr effect. A single Ag particle of -30 nm diameter was chosen as a SNOM probe for reasons unique to magnetic imaging. Sub-wavelength Ag particles interact strongly with incident light due to an effect called the localized surface plasmon resonance. An apparatus is described for the characterization of the plasmon resonance in isolated Ag particles. Data obtained from the apparatus is presented and present work in the measurement of the magneto-optic Kerr effect in a near-field geometry is described.
