Optical detection of the electron spin resonances of G centers in silicon
Félix Cache, Krithika V. R., Tobias Herzig +8
Color centers in silicon are emerging as promising platforms for quantum technologies. Among them, the G center has attracted considerable interest owing to its bright telecom O-ba…

A single optically detectable tumbling spin in silicon
Félix Cache, Yoann Baron, Baptiste Lefaucher +9
We demonstrate single spin spectroscopy of a fluorescent tumbling defect in silicon called the G center, behaving as a pseudo-molecule randomly reorienting itself in the crystallin…

Room temperature magnetic vortices in the van der Waals magnet FeGeTe
Elias Sfeir, Carolin Schrader, Florentin Fabre +8
We investigate the effect of confinement on the magnetic state of a 12 nm-thick FeGeTe layer grown by molecular beam epitaxy. We use quantitative scanning NV magnetometry t…
