Suppression of Dynamically Induced Stochastic Magnetic Behavior Through Materials Engineering

“…To examine this, we considered the 10 x 10 µm 2 ends. These represented more generic examples of mesoscopic magnetic systems, and were expected to exhibit complex 2-dimensional magnetisation states, 52 the details of which would dictate the manner in which DWs were injected into the nanowires. Thus, the widths of IFDs were expected to offer a probe of how stochastic the switching behaviours of these large, complex magnetic microstructures were.…”

Microscale Magneto-Elastic Composite Swimmers at the Air-Water and Water-Solid Interfaces Under a Uniaxial Field

“…Note, however, that these measurements are taken on pinned particles and that rotation of freely moving swimmers during alignment with the field will generate field components transverse to the easy axis of the particles. Since even small transverse fields can dramatically change domain structure and reversal field [24,25], switching of the Co particle in swimmers may occur at lower fields.…”

High numerical aperture reflection mode coherent diffraction microscopy using off-axis apertured illumination

“…Our non-contact technique images a pinhole onto the sample plane, resulting in no damage to the sample and no restriction of the NA of the imaging system, while our advances in the algorithms enable rapid image reconstruction and an ability to correct the diffraction pattern for sample tilt that is inherent to high-NA imaging. These advances are important because high-NA reflection mode CDI has many potential applications for example as a nanometrology tool for future generations of semiconductor patterning [31], for dynamic imaging of magnetic domains [14,32] or catalytic surfaces, and for use when the sample is thicker than the absorption length of the illuminating light.…”
