The relation between magnetic hysteresis and the micromagnetic state explored by quantitative magnetic force microscopy [PDF]
, 2006 Since the discovery of magnetic lodestones in 600 BC described by ancient Greek philosophers, the mystery of magnetism has continued to intrigue. For thousands of years, these lodestones were more of a curiousity until medieval explorers discovered ...

Time‐Resolved Magnetization Switching Dynamics Driven by Orbital Torques
Advanced Functional Materials, EarlyView.Du et al. reveal nanosecond magnetization switching driven by orbital currents using time‐resolved Hall detection. The measurements separate domain nucleation from domain wall propagation and show that Joule heating strongly assists switching by lowering energy barriers.

Advanced Functional Materials, EarlyView.A cooperative and competitive interrelationship between alcohol oxidation (AOR) and water oxidation (OER) was observed on a typical anode catalyst of Ni2P. In situ Raman spectroscopy and electrochemical analyses revealed a specific complementary mechanism between them, in which OER and AOR critically contribute to the activity and stability of anodic ...

Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Advanced Functional Materials, EarlyView.Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward
