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,

A Magnetoelastic Twist on Magnetic Noise: The Connection with Intrinsic Nonlinearities

Advanced Functional Materials, Volume 34, Issue 9, February 26, 2024.
Magnetoelastic nonlinearity significantly limits the performance of devices that use ferromagnetic films as sensitive elements. By introducing a comprehensive theory of magnetic noise in sensor systems, previously unrecognized noise sources linked to magnetoelasticity are revealed.
