Samples for the MOKE and MFM

Sample preparation for the MOKE and MFM is a very tricky business. Not only is it vital to get a smooth (and relatively unstressed) surface, it is also vital to have the scanned surface oriented parallel to the crystallographic easy (magnetization) direction of the grain. If this is not done, strange domain patterns can be observed as a result of the sample plane cutting domains at an angle. If you really want to come to the IRM to use either of these instruments, please contact Bruce Moskowitz for details about preparation of samples.
