Development of a Three‐Axis Planar Hall Magnetoresistance Sensor Using a Superparamagnetic Nanoparticle‐Based Flux Guide

Advanced Functional Materials, EarlyView.
A printed superparamagnetic nanoparticle‐based flux guide enables the realization of a hysteresis‐free three‐axis magnetic sensor. This innovative architecture efficiently redirects out‐of‐plane fields to planar sensing elements, facilitating simultaneous vector detection without complex reset protocols.

Toward Enhanced Inertial Sensing via Dynamically Soft Topological States in Piezoelectric Microacoustic Metamaterials

Advanced Functional Materials, EarlyView.
A piezoelectric microacoustic wave device exploiting topologically protected interface states with significantly higher dynamic compliance than Lamb or Rayleigh modes achieves record‐high out‐of‐plane particle velocities exceeding 51 m/s. These findings indicate that leveraging topological interface states can overcome key limitations of piezoelectric ...

Effect of Optical Illumination on Bubble Nanodomains

Advanced Functional Materials, EarlyView.
Stable surface‐confined nanoscale bubble domains are created and manipulated in PMN‐PT single crystals. Under above‐bandgap illumination, these bubble nanodomains remain unchanged. However, upon illumination cessation, they rapidly expand to switch the entire crystal surface, due to the accumulation of a large reservoir of electrons at the crystal ...
