Main text This report describes the second CCM key comparison of realizations of the kilogram definition based on the fixed numerical value of the Planck constant, which came into force on 20 May 2019. The objectives were to determine the level of ag

We present characterization of the hyperfine and quadrupole interactions of praseodymium in La 2 ( WO 4 ) 3 . The hyperfine structure of the H 4 3 ( 0 ) → 1 D 2 ( 0 ) transition is calculated from a crystal-field analysis and is compared to experim

We observe the two- and three-pulse photon echo emission from a scattering powder, obtained by grinding a Pr$^{3+}$:Y$_2$SiO$_5$ rare earth doped single crystal. We show that the collective emission is coherently constructed over several grains. A we

We have studied a rare-earth-doped crystal, Pr3+:La-2(WO4)(3), which exhibits a high magnetic-moment density. Although the latter favors rare-earth dephasing, a nuclear-spin coherence lifetime of 250 mu s has been observed, as well as electromagnetic

We report the direct observation of Er-Y and Er-Si interactions in $\mathrm{Er}:{\mathrm{Y}}_{2}\mathrm{Si}{\mathrm{O}}_{5}$ by spin-echo measurements. Modulations in the spin-echo decay of ${\mathrm{Er}}^{3+}$ ions are due to magnetic interactions b
