Electrical Detection of Magnetic Skyrmions in a Magnetic Tunnel Junction

Magnetic skyrmions are promising information carriers for dense and energy-efficient information storage owing to their small size, low driving-current density, and topological stability.* Electrical detection… Read More »Electrical Detection of Magnetic Skyrmions in a Magnetic Tunnel Junction

Figure 4 from “Magnetic Skyrmions in a Thickness Tunable 2D Ferromagnet from a Defect Driven Dzyaloshinskii–Moriya Interaction” by Anirban Chakraborty et al. Thickness dependence of skyrmion size in lamella L2 as imaged by MFM. a) SEM image of the wedge-shaped lamella. The thickness of the lamella varies from ≈100 nm to ≈2 µm. b) MFM image of skyrmions in the lamella at 100 K and 0.032 T. c–f) Evolution of skyrmions as the field is increased from 0.1 to 0.2 T and finally reaches the field polarized state at ≈0.3 T. The blue and red contrast in the MFM images represent up- and down-magnetized domains. All MFM images are at the same scale: a scale bar is shown in (b). g) Skyrmion diameter as a function of lamella thickness including both MFM and LTEM data. NANOSENSORS SSS-MFMR AFM probes for magnetic force microscopy were used for all MFM measurements.

There is considerable interest in van der Waals (vdW) materials as potential hosts for chiral skyrmionic spin textures. Of particular interest is the ferromagnetic, metallic… Read More »Magnetic Skyrmions in a Thickness Tunable 2D Ferromagnet from a Defect Driven Dzyaloshinskii–Moriya Interaction

Fig. 6 from “On the magnetic nanostructure of a Co–Cu alloy processed by high-pressure torsion” by Martin Stückler et al.: 2 μm × 2 μm AFM scans of (a) as-deformed state and (c) 300 °C annealed state. The corresponding MFM scans of the as-deformed and 300 °C annealed state are shown in (b) and (d) respectively. The axial direction of the HPT specimen points out of the plane, the shear direction is in horizontal direction. The lateral scale bar in (a) applies to all scans. The minimum height and phase signal values are shifted to zero for visualization purposes. NANOSENSORS SSS-MFMR magnetic AFM probes optimized for high resolution magnetic force microscopy were used

Lately the production of nanocrystalline magnetic materials starting with coarse grained materials (top-down approach) has received increasing interest.* The advantage of the top-down approach compared… Read More »On the magnetic nanostructure of a Co–Cu alloy processed by high-pressure torsion
