Probing Near‐Field EM Fluctuations in Superparamagnetic CoFeB With NV Quantum Dephasometry
Advanced Optical Materials, EarlyView.We non‐invasively investigate the superparamagnetic spin dynamics of a 1.1 nm CoFeB layer by probing its near‐field EM fluctuations using NV centers‐based quantum dephasometry. Our findings are further supported by theoretical modeling and SQUID‐based magnetization characterization. These results provide critical insight into the magnetization dynamics

Luminescence and Photochromism in Lanthanide‐Doped Hackmanites
Advanced Optical Materials, EarlyView.Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.
