"abstract": "<p>We have measured inhomogeneous linewidths and coherence times (T<sub>2</sub>) of nuclear spin transitions in a Eu<sup>3+</sup>:Y<sub>2</sub>O<sub>3</sub> transparent ceramic by an all-optical spin echo technique. The nuclear spin echo decay curves showed a strong modulation which was attributed to interaction with Y nuclei in the host. The coherence time of the 29 MHz spin transition in <sup>151</sup>Eu<sup>3+</sup> was 16 ms in a small applied magnetic field. Temperature dependent measurements showed that the coherence time was constant up to 18 K and was limited by spin-lattice relaxation for higher temperatures. Nuclear spin echoes in <sup>153</sup>Eu<sup>3+</sup> gave much weaker signals than for the case of <sup>151</sup>Eu<sup>3+</sup>. The spin coherence time for the 73 MHz spin transition in <sup>153</sup>Eu<sup>3+</sup> was estimated to 14 ms in a small magnetic field. The study shows that the spin transitions of ceramic Eu<sup>3+</sup>:Y<sub>2</sub>O<sub>3</sub> have coherence properties comparable to the best rare-earth-doped materials available.</p>\n\n<p>These results have been highlighted in JPhys+, news and views from the Journal of Physics series (IOP):\u00a0https://jphysplus.iop.org/2017/02/09/long-spin-coherence-lifetime-in-eu3y2o3-ceramic/</p>\n\n<p>\u00a0</p>",
