Hidden Charge‐Order in the Mixed‐Valent K0.75Li2Cr6O12 High‐Pressure Oxide
Advanced Science, EarlyView.K0.75Li2Cr6O12 is one of the few mixed valent chromium oxides. It shows a single angle spiral magnetic structure with a k = [1/3 1/3 ¼] propagation vector. Density functional theory reveals a hidden charge order that is necessary to stabilize the antiferromagnetic (AFM) ground state.

Structure‐Function Integration in 2D Hybrid Perovskite for Fast Neutron and Gamma Ray Discrimination
Advanced Science, EarlyView.Using an in situ seed‐assisted cooling method, large (28 × 7 × 3 mm3) (GABA)2PbBr4 single crystals are grown, featuring hydrogen‐rich organic layers and a dense PbBr4 framework. This architecture enables efficient γ‐ray absorption, fast‐neutron sensitivity, and clear n/γ pulse‐shape discrimination (FOM up to 1.74), highlighting its potential as a ...

Ultrafast Control of Néel Vector in Collinear Antiferromagnet MnPt
Advanced Science, EarlyView.Direct evidence of ultrafast manipulation of the antiferromagnetic order parameter (Néel vector) in an exchange bias system is demonstrated using terahertz (THz) emission spectroscopy. Laser‐induced torque cants the Néel vector in the collinear antiferromagnet MnPt, generating a transient magnetic moment that produces THz radiation. This study provides

Deciphering the small-angle scattering of polydisperse hard spheres using deep learning
APL Machine LearningWe introduce a deep learning approach for analyzing the scattering function of the polydisperse hard sphere system. We use a variational autoencoder-based neural network to learn the bidirectional mapping between the scattering function and the system ...
