Magnetization Plateaus by the Field-Induced Partitioning of Spin Lattices [PDF]

arXiv
To search for a conceptual picture describing the magnetization plateau phenomenon, we surveyed the crystal structures and the spin lattices of those magnets exhibiting plateaus in their magnetization vs. magnetic field curves by probing the three questions: (a) why only certain magnets exhibit magnetization plateaus, (b) why there occur several ...

Magnetoelastic Sensing: A Study of Flexible Magnetoelastic Strain Sensors for Highly Deformed Posture Perception

Advanced Materials Technologies, EarlyView.
This study proposes a magnetoelastic strain sensor for highly deformed posture perception. The sensor can maintain stable sensing signal output under significant strain (200%) and at varying stretch rates (ranging from 1000 to 8000 mm min−1). The sensor design is simple and can be applied to soft robots and wearable devices.

Complex Assemblies of Colloidal Microparticles with Compliant DNA Linkers and Magnetic Actuation

Advanced Materials Technologies, EarlyView.
High‐surface‐energy polycarbonate templates are used to assemble polystyrene microspheres, improving yields more than 100‐fold. These higher yields facilitate the construction of active colloids and complex microstructures, including 10‐sphere microrotors and a 26‐sphere “CMU.” These active colloids are connected with compliant DNA linkages, enabling ...

A MEMS Electromagnetic Vibration Energy Harvester with Monolithically Integrated NdFeB Micromagnets

Advanced Materials Technologies, EarlyView.
50µm thick sputtered arrays of NdFeB micromagnets are directly integrated into a functional MEMS in‐plane electromagnetic vibration energy harvester. A combination of analytical modeling and numerical simulations guided the design of the magnet arrays and ad‐hoc coil, to produce a high transduction factor.

Magnetic Force‐Induced Self‐Assembly and Flip‐Chip Alignment on Electroplated Multilayer Solder with Tailored Melting Points

Advanced Materials Technologies, EarlyView.
This work demonstrates fluidic self‐assembly and self‐alignment of flip‐chips using a magnetic field for agitation and orientation. Pb‐free solder bumps with tailored transformation imprinted melting points enable selective capturing on low‐melting solder in water. After capturing, final alignment is achieved through magnetic forces.
