Advanced Science, EarlyView.MnRhP has been identified as a novel kagomé magnet that hosts magnetic skyrmions above room temperature and exhibits a large intrinsic anomalous Hall effect. The latter originates from Berry curvature associated with gapped nodal lines, establishing MnRhP as a promising platform for exploring high‐temperature topological phenomena in both real and ...

Strain‐Assembled Crystalline SrRuO3 Microtube and Emergent Curvilinear Magnetism
Advanced Science, EarlyView.The interfacial‐strain assembly based on planar nanomembranes presents a promising approach for constructing novel magnetic microstructures. By employing the perpendicular magnetic anisotropic SrRuO3 freestanding nanomembrane as a model system, we exploit the interfacial strain effect within the crystalline SrTiO3/SrRuO3 bilayer, and successfully ...

Low-temperature demagnetization and ice-pressure demagnetization in magnetite and haematite [PDF]
Geophysical Journal International, 1994 SUMMARY Low-temperature demagnetization (LTD) is confirmed as an effective method of removing soft (low coercivity) components of remanence in magnetite-bearing specimens by passing the magnetite through its low-temperature transition (?130 K). Haematite has its low-temperature transition at approximately 258 K.

Fe‐Based Nanocrystalline Magnetic Shielding Cylinder with Subfemtotesla‐Level Magnetic Noise
Advanced Science, EarlyView.Shields with low magnetic noise are achieved by integrating Fe‐based nanocrystalline magnetic shielding cylinders into shielding systems based on μ‐metal. Benefiting from high permeability and low loss factor, Fe‐based nanocrystalline magnetic shielding cylinders effectively suppress magnetic noise. Notably, the magnetic shielding cylinder with the ten‐
