Theoretical limits of magnetic detection of structural surface defects at the nanometer scale
Wolfgang Körner, Daniel F. Urban, Christian Elsässer
We present a theoretical study on the magnetic signals of structural surface defects like cracks or indents combined with rough surfaces or subsurface inclusions of soft ferromagne…
