Raman Fingerprints of Phase Transitions and Ferroic Couplings in Van der Waals Material CuCrPS
Jing Tang, Benjamin J Lawrie, Mouyang Cheng +9
CuCrPS (CCPS), a type-II multiferroic material, exhibits unique phase transitions involving ferroelectric, antiferroelectric, and antiferromagnetic ordering. In this study,…
Probing Boron Vacancy Defects in hBN via Single Spin Relaxometry
Alex L. Melendez, Ruotian Gong, Guanghui He +14
Spin defects in solids offer promising platforms for quantum sensing and memory due to their long coherence times and optical addressability. Here, we integrate a single nitrogen-v…
Defect Engineering in Large-Scale CVD-Grown Hexagonal Boron Nitride: Formation, Spectroscopy, and Spin Relaxation Dynamics
Ivan V. Vlassiouk, Yueh-Chun Wu, Alexander Puretzky +19
Recently, numerous techniques have been reported for generating optically active defects in exfoliated hexagonal boron nitride (hBN), which hold transformative potential for quantu…
Non-perturbative cathodoluminescence microscopy of beam-sensitive materials
Malcolm Bogroff, Gabriel Cowley, Ariel Nicastro +9
Cathodoluminescence microscopy is now a well-established and powerful tool for probing the photonic properties of nanoscale materials, but in many cases, nanophotonic materials are…
Nanoscale magnetic ordering dynamics in a high Curie temperature ferromagnet
Yueh-Chun Wu, Gábor B. Halász, Joshua T. Damron +11
Thermally driven transitions between ferromagnetic and paramagnetic phases are characterized by critical behavior with divergent susceptibilities, long-range correlations, and spin…
