Simultaneous magnetic field and field gradient mapping of hexagonal MnNiGa by quantitative magnetic force microscopy
Abstract
A quantitative magnetic force microscopy technique is presented that maps one magnetic stray-field component and its spatial derivative at the same time. Furthermore, this technique is applied to investigate individual circular magnetic nano-domains in MnNiGa bulk samples providing bubble diameters and the spatial extent in depth.
