LeXtender: a software package for advanced MOKE acquisition and analysis

Abstract

Abstract Contemporary scanning laser Kerr magnetometers are very efficient measurement devices that achieve very good signal to noise ratios and spatial resolution for magnetization measurements. When going beyond simple hysteresis loop measurements, large amounts of data can be acquired quickly and, thus, control software and automated processing becomes necessary to go beyond these simple measurements. Here, we present an open source software that realizes first-order reversal curves and magnetic property mapping based on scanning laser Kerr magnetometry. The modular software is easily extensible and provides a convenient user interface to make these more complex measurements accessible to a broader user base.
