Figure 4. from Ajesh K. Gopi et al. 2024: (a–e) MFM images of a bulk crystal with thickness ∼170 μm recorded at 100 K in the presence of an external field. Numbers in the upper right corner of each image show the corresponding field strength. (f) Magnified images of two selected regions (2 μm × 2 μm) in (e) showing two distinct magnetic contrasts. (g) Schematic representation showing the sample hosting different magnetic textures that result in different magnetic contrasts in MFM measurements. NANOSENSORSTM SSS-MFMR, a magnetic AFM probe with an AFM tip radius of curvature < 15 nm was used for all measurements.

The family of two-dimensional (2D) van der Waals (vdW) materials provides a playground for tuning structural and magnetic interactions to create a wide variety of… Read More »Thickness-Tunable Zoology of Magnetic Spin Txtures Observed in Fe5GeTe2
