Scanning magnetoresistance microscopy (SMRM) is a powerful imaging technique, that uses conventional hard disk drive recording heads as a sensor for raster scanning in physical contact with a magnetic film sample. The modern vintages of MR heads are capable of reaching the resolution down to 15 nm in down-track direction, what is comparable with magnetic force microscopy. The unique ability to apply a localized field up to 1 T to the sample makes this tool attractive for recording experiments on continuous films as well as on nanostructures. Thanks to the high bandwidth of the embedded inductive coil system, ultra short magnetic field pulses in the sub-ns range can be applied. This fact allows using this setup as a research instrument for studying dynamic magnetization reversal processes on the nanoscale.
