Light‐Modulated Exchange Bias in Multiferroic Heterostructures
In this article, exchange bias and magnetization are modulated with visible light at room temperature in PMN‐PZT/FeGa/IrMn multiferroic heterostructures. Photostrictive effect is the main mechanism leading to the modulation of magnetic anisotropy and interfacial exchange bias coupling between the ferromagnetic and antiferromagnetic layers.

The Impact of Monetary Policy Shocks on Stock Price Crash Risk
ABSTRACT This study examines the impact of monetary policy shocks (MPS) on future stock price crash risk (SPCR), using a sample of US firms from 1995 to 2019. We find that expansionary MPS significantly reduce the likelihood of SPCR, while contractionary MPS show no statistically significant effect on SPCR. These results remain robust after controlling

Perls–TEM–STEM‐HAADF–EDS enables high‐resolution localization and elemental characterization of Fe‐containing deposits in Rhizophora mangle leaf cells. ABSTRACT Mangrove ecosystems are frequently exposed to high concentrations of iron (Fe) in sediments, resulting in Fe accumulation in plant tissues. Although Fe is an essential micronutrient involved in
