Characteristics of long-lived persistent spectral holes in $E u^{3 +} : Y_{2} S i O_{5}$ at $1.2 K$

René Oswald, Michael Hansen, Eugen Wiens +2

Properties of persistent spectral holes (SHs) relevant for frequency metrology have been investigated in the system $E u^{3 +} : Y_{2} S i O_{5}$ (0.5%) at crystallographic site 1 and a t…
