Room-temperature multistage metastability in a moiré superstructure
B. Q. Lv, Yifan Su, Alfred Zong +16
Metastability is fundamental not only to phase ordering and transitions, but also to a broad range of modern technologies, from memory devices to metallic glasses. In condensed-mat…
Stoichiometry-Controlled Structural Order and Tunable Antiferromagnetism in ()
Xiaotong Xu, Bei Jiang, Runze Wang +4
Transition metal dichalcogenides (TMDs) enable magnetic property engineering via intercalation, but stoichiometry-structure-magnetism correlations remain poorly defined for Fe-inte…
Higgs-mode electromagnon in the spin-spiral multiferroic CuBr
Bryan T. Fichera, Ajesh Kumar, Baiqing Lv +8
Below a continuous symmetry breaking phase transition, the relevant collective excitations are due to longitudinal and transverse fluctuations of the order parameter, which are ref…
Automated Polarization Rotation for Multi-Axis Rotational-Anisotropy Second Harmonic Generation Experiments
Karna A. Morey, Bryan T. Fichera, Baiqing Lv +2
Rotational anisotropy second harmonic generation (RA-SHG) is a nonlinear optical technique used to probe the symmetry of condensed matter systems. Measuring the dependence of the S…
Light-induced reorientation transition in an antiferromagnetic semiconductor
Bryan T. Fichera, Baiqing Lv, Karna Morey +18
Due to the lack of a net magnetic moment, antiferromagnets possess a unique robustness to external magnetic fields and are thus predicted to play an important role in future magnet…
Direct observation of a photoinduced topological phase transition in Bi-doped (Pb,Sn)Se
Masataka Mogi, Dongsung Choi, Louis Primeau +6
Ultrafast photoexcitation offers a novel approach to manipulating quantum materials. One of the long-standing goals in this field is to achieve optical control over topological pro…
