The Coupling of Ferroelectric Polarization and Oxygen Vacancy Migration Enables Electrically Controlled Thermal Memories

Advanced Materials, Volume 38, Issue 24, 27 April 2026.
Ferroelectric Hf0.5Zr0.5O2 epitaxial thin films exhibit a non‐volatile, electrically controlled thermal conductivity enabled by the coupling between oxygen vacancy migration, acting as phonon scatterers, and ferroelectric polarization, acting as ion migration valve.

Cryogenic Focused Ion Beam Milling to Investigate the Anisotropic Magnetotransport Properties of Bismuth Microcrystals

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
The highly anisotropic Fermi surface of bismuth results in variations in magnetotransport properties across different crystallographic directions, which can be characterized by studying microcrystals. To avoid the observed surface melting under room temperature Focused Ion Beam (FIB) irradiation, two low‐temperature FIB fabrication methods are proposed
