Eos, Transactions American Geophysical Union, 1989 At the recently concluded International Association of Geomagnetism and Aeronomy Assembly in Exeter, U.K., magnetic domain observations on magnetite imaged for the first time by the magneto‐optic Kerr effect were reported. The picture (Figure 1) shows domains on a synthetic magnetite grain where magnetic contrast is achieved by the longitudinal Kerr ...

Weak Magnetic Anomaly Signal Extraction Method Based on EEMD and DWT
水下无人系统学报, 2023 Magnetic anomaly signal contains rich feature information of targets, which is the basis for target localization and identification. However, the magnetic anomaly generated by the target rapidly attenuates with detection distance, making the weak ...

Influence of topography and Co domain walls on the magnetization reversal of the FeNi layer in FeNi/Al$\_2$O$\_3$/Co magnetic tunnel junctions [PDF]
, 2006 We have studied the magnetization reversal dynamics of FeNi/Al$\_2$O$\_3$/Co magnetic tunnel junctions deposited on step-bunched Si substrates using magneto-optical Kerr effect and time-resolved x-ray photoelectron emission microscopy combined with x-ray

Controlled switching of N\'eel caps in flux-closure magnetic dots [PDF]
, 2009 While magnetic hysteresis usually considers magnetic domains, the switching of the core of magnetic vortices has recently become an active topic. We considered Bloch domain walls, which are known to display at the surface of thin films flux-closure ...
