Detection of magnetic field for measuring current distribution in metal nanostructure

Magnetic Properties of Poly (Divinylbenzene, Ethylene Glycol Dimethacrylate and Vinyl Alcohol) Containing Barium Ferrite Nanoparticles

“…The MFM tip is coated with Al. In order to observe magnetic domain patterns, the tip trace the sample surface four times [14]. MFM imaging mode is based on tapping mode.…”

Detection of nonmagnetic metal thin film using magnetic force microscopy

“…4 of Ref. 4). They attributed the observed small signals in the absence of current to an effect of surface topography, although they did not specify this effect exactly.…”

“…Magnetic force microscopy (MFM) is often used for detecting stray magnetic fields near the surfaces of magnetic materials, [1][2][3] with a magnetized tip oscillating above the material. However, in their investigation of the currentinduced magnetic field from nonmagnetic metal lines, Tanaka et al 4 reported that MFM can detect small signals from nonmagnetic materials (see Fig. 4 of Ref.…”

“…5]. However, neither Tanaka et al 4 nor Stiller et al 5 discussed the origin of the observed small signals in the absence of magnetic materials and of currents. In the present work, such MFM signals from a thin film of nonmagnetic metal are shown to originate from eddy currents induced in the film by the oscillating MFM tip.…”
