Development opportunity
German researchers have succeeded in reducing the number of layers required to create a magnetic coating in a sensor to one, a development that is expected to make it possible to manufacture more powerful magnetic sensors.
Currently, magnetic multilayer systems for magnetic sensors are comprised of individual films, which are often only a few atomic layers thick. Now scientists from the Leibniz Institute of Solid State and Materials Research, Dresden and from the Forschungszentrum Dresden-Rossendorf, have worked out how to combine the magnetic properties of each different layer materials within a single film.
The single layer, combining hard and soft magnetic properties, is generated by means of ion implantation on a micrometre scale. The scientists now want to generate the layer at a nanometre scale, where they expect to see new properties emerging.
