Direct observation of domain walls in NiFe films using high-resolution Lorentz microscopy
A novel approach to observe the interaction between magnetic domain wall and nanoscale microstructural features is demonstrated. The method is based on Focault mode Lorentz microscopy and utilizes a Gatan energy image filter to provide additional magnification. A postexperimental image processing technique was applied to separate lattice diffraction from that induced by magnetic domains. The ef...
متن کاملNanomechanics of Amyloid Materials Studied by Atomic Force Microscopy
Amyloids are usually used to refer to a wide range of fibrous nanostructures formed from natural and synthetic proteins and peptides. The self-propagating protein aggregates are rich in ┚-sheets, which stack in hundreds to thousands units perpendicular to the fibrous axis, forming fibrils 5-15 nm in width and several micrometers in length (Dobson, 1999; Jaroniec et al., 2004; Luhrs et al., 2005...
متن کاملHigh Resolution Quantitative Lorentz Microscopy
The advent of aberration corrected transmission electron microscopy has led to considerable improvements in the field of high resolution electron microscopy imaging. In this paper we show how these developments are applied to imaging of magnetic structure in field free or low field conditions. Whilst the capability of increased spatial resolution is demonstrated on magnetic layers with a width ...
متن کاملRecent Progress in Lorentz Transmission Electron Microscopy
After a brief review of the basic methods of Lorentz transmission electron microscopy (LTEM), including the Transport-of-Intensity formalism for phase reconstruction, we present a few examples of the application of LTEM to multiferroic materials, in this case ferromagnetic shape memory alloys. We discuss observations of magnetic domain walls pinned to anti-phase boundaries in Ni2MnGa, and domai...
متن کاملMagnetic domain observations in a FeCo-based nanocrystalline alloy by Lorentz microscopy
Lorentz microscopy was used to investigate the domain structure in an Fe0.5Co0.5 80Nb4B13Ge2Cu1 alloy annealed at 500, 550, and 610 °C, respectively, for 1 h. The average grain size d, observed by conventional transmission electron microscopy, is 10 nm for the alloy annealed at 500 °C, 18 nm for 550 °C, and 90 nm for 610 °C. The domain structure of sample annealed at 500 °C exhibits few pinning...
