Observation of stable Néel skyrmions in cobalt/palladium multilayers with Lorentz transmission electron microscopy
Néel skyrmions are of high interest due to their potential applications in a variety of spintronic devices, currently accessible in ultrathin heavy metal/ferromagnetic bilayers and multilayers with a strong Dzyaloshinskii-Moriya interaction. Here we report on the direct imaging of chiral spin structures including skyrmions in an exchange-coupled cobalt/palladium multilayer at room temperature w...
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 کاملElectron Diffraction Using Transmission Electron Microscopy
Electron diffraction via the transmission electron microscope is a powerful method for characterizing the structure of materials, including perfect crystals and defect structures. The advantages of electron diffraction over other methods, e.g., x-ray or neutron, arise from the extremely short wavelength (≈2 pm), the strong atomic scattering, and the ability to examine tiny volumes of matter (≈1...
متن کاملImaging Perpendicular Magnetic Domains in Plan-view Using Lorentz Transmission Electron Microscopy
The study of magnetic materials requires an understanding of not only their magnetic properties, but also their microstructure. Transmission electron microscopy (TEM) is a powerful characterization instrument because of its ability to provide both microstructural and magnetic information. In TEM, electrons can be deflected by a Lorentz force created by a magnetic field from a magnetic material....
متن کاملDiagnostic Transmission Electron Microscopy
The high resolution and sensitivity of electron microscopy is still a valuable tool, and for some diseases it is the gold standard in pathological diagnosis. Today the sample turnaround time for processing in the lab can be significantly reduced from days to hours by the microwave technology. In urgent clinical cases, microwaveassisted tissue processing, in combination with digital image acquis...
