Torsion Dependence of Domain Transition and MI Effect of Melt‐Extracted Co68.15Fe4.35Si12.25B13.25Nb1Cu1 Microwires

Advances in Materials Science and Engineering, Volume 2015, Issue 1, 2015., 2015
We present the torsional stress induced magnetoimpedance (MI) effect and surface domain structure evolution of magnetostrictive melt‐extracted Co68.15Fe4.35Si12.25B13.25Nb1Cu1 microwires. Experimental results indicate that the surface domain structures observed by magnetic force microscope (MFM) transform from the weak circumferential domain of as‐cast

Laser‐Guided Self‐Assembly of Thin Films into Micro‐Rolls

Advanced Functional Materials, Volume 34, Issue 19, May 10, 2024.
Combining laser scribing techniques and strain engineering techniques, a laser‐guided self‐assembly strategy is developed to manufacture 3D micro‐rolls from thin films. This dry‐release strategy is highly scalable and viable in the atmosphere, and achieves precise control of self‐assembly behavior (including self‐rolling areas, curvatures, orientations,
