Advanced Functional Materials, Volume 36, Issue 33, 23 April 2026.This study demonstrates coherent control of 15N nuclear spins coupled to VB−${\text{V}}_{\text{B}}^{-}$ centers in isotope‐enriched hexagonal boron nitride. Selective addressing via spin‐state mixing enables Rabi driving, quantum gates, and coherence times exceeding 10 μs$\umu{\rm s}$.

Large Field‐Like Orbital Torque in FeNi/Cr Heterostructures
Advanced Electronic Materials, Volume 12, Issue 7, 6 April 2026.Orbital torque enables field‐free magnetization switching in spintronics. FeNi/Cr heterostructures exhibit a large field‐like orbital torque. This torque originates from a tilted orbital current polarization within the Cr layer, producing a significant z‐component.

Analog Control of Reconfigurable GHz Resonances from Chiral Spin Texture Ensembles
Advanced Materials, Volume 38, Issue 18, 25 March 2026.Tunable microwave components ‐ essential for wireless technology ‐ typically require costly, customized nanofabrication. We show that ambient spin texture ensembles (e.g., magnetic skyrmions) in chiral multilayer films can enable reconfigurable microwave resonators.
