Introduction
This website is dedicated to my primary research interest, science & technology on the nanometer scale. On these pages you'll find brief descriptions of my past and present projects. Thanks for visiting.
Composite Multiferroics
Electric field control of magnetization can be achieved by combining a magnetostrictive film with a piezoelectric film. The strain response of the piezoelectric substrate upon application of an electric field, is transferred to the magngetostrictive film, hence altering the magnetic anisotropy of the film.
Magneto Optical Kerr Effect
Magnetic characterization of thin film samples using the Kerr effect. For transparent samples, the Faraday effect can be measured. Polar, longitudinal as well as transverse MOKE geometry is supported. Magnetic field sweep range +/- 2 Tesla. Temperature control from liquid He up to 400K.
Magneto Resistance
Measuring the Magneto resistance (MR) is a convenient way to characterize thin magnetic films. By combining the MOKE setup with MR measurements, the interpretation of both the MOKE and MR data can be simplified.
