AC Current‐Driven Magnetization Switching and Nonlinear Hall Rectification in a Magnetic Topological Insulator

open access: yesAdvanced Materials, Volume 38, Issue 4, 16 January 2026.
This study reports alternating‐current (AC) driven magnetization reversal in a semi‐magnetic topological insulator (Cr,Bi,Sb)2Te3/(Bi,Sb)2Te3, with low current density. Time‐domain Hall voltage measurements reveal a nonlinear and rectified Hall effect, along with higher‐harmonic responses and hysteresis.

On‐Chip Perovskite Coolers

open access: yesAdvanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.
Scaling of 3D‐integrated electronics exacerbates thermal bottlenecks, motivating solid‐state on‐chip cooling beyond convection and immersion. This perspective reviews optical refrigeration, electroluminescent cooling, and thermoelectrics for localized, vibration‐free heat removal.

Efficient Broadband Terahertz Generation by Above‐Band‐Gap Excitation of the Pyroelectric ZnSnN2

open access: yesAdvanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
Photo‐induced THz emission from the pyroelectric semiconductor ZnSnN2 is studied. For above‐band‐gap excitation, an ultrabroadband THz pulse is generated covering the range from 1 to 30 THz without any spectral gaps. The THz‐generation efficiency is about three orders of magnitude higher than that from a standard THz source like ZnTe with a similar ...

Obtaining Orthogonal Thermal Conductivity Components from Anisotropic Thin Films Using the Pseudo Steady‐State 3ω Method

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 1, January 2026.
Measurement of thin film thermal conductivity is challenging for isotropic materials, but is even more so for films with anisotropic in‐plane properties. This work establishes the pseudo steady‐state 3ω technique as a suitable method to extract orthogonal in‐plane thermal conductivity components from thin films. Abstract Directional characterization of

Lithium and Vanadium Intercalation into Bilayer V2Se2O: Ferrimagnetic–Ferroelastic Multiferroics and Anomalous and Spin Transport

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
Li‐ and V‐intercalated V2Se2O bilayers possess intralayer ferrimagnetic and interlayer ferromagnetic orders, alongside ferroelasticity, in‐plane uniaxial magnetic anisotropy, half‐metal/enhanced spin splitting, the anomalous Hall effect, giant magnetoresistance, tunneling magnetoresistance, near‐perfect spin filtering effect, spin Seebeck effect, and ...

Breath, Pulse, and Speech: A Multi‐Parameter Wearable System using Airflow‐Thermoelectric Fusion Technology

open access: yesAdvanced Science, Volume 13, Issue 4, 19 January 2026.
For insufficient medical emergency monitoring, this study develops a wearable system with flexible thermoelectric textiles and thermoelectric‐optical sensing. It establishes a dynamic airflow‐thermoelectric response theory (enabling 98% speech recognition) and a multi‐source fusion model for 98% emergency state recognition, aiding clinical decision ...
