Superhyperfine induced photon-echo collapse of erbium in YSiO
B. Car, J. -L. Le Gouët, T. Chanelière
We investigate the decoherence of Er in YSiO at low magnetic fields using the photon-echo technique. We reproduce accurately a variety of the decay curves with a uni…
Optical study of the anisotropic erbium spin flip-flop dynamics
B. Car, L. Veissier, A. Louchet-Chauvet +2
We investigate the erbium flip-flop dynamics as a limiting factor of the electron spin lifetime and more generally as an indirect source of decoherence in rare-earth doped insulato…
