    <description descriptionType="Abstract">&lt;p&gt;We have measured inhomogeneous linewidths and coherence times (T&lt;sub&gt;2&lt;/sub&gt;) of nuclear spin transitions in a Eu&lt;sup&gt;3+&lt;/sup&gt;:Y&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt; 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 &lt;sup&gt;151&lt;/sup&gt;Eu&lt;sup&gt;3+&lt;/sup&gt; 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 &lt;sup&gt;153&lt;/sup&gt;Eu&lt;sup&gt;3+&lt;/sup&gt; gave much weaker signals than for the case of &lt;sup&gt;151&lt;/sup&gt;Eu&lt;sup&gt;3+&lt;/sup&gt;. The spin coherence time for the 73 MHz spin transition in &lt;sup&gt;153&lt;/sup&gt;Eu&lt;sup&gt;3+&lt;/sup&gt; was estimated to 14 ms in a small magnetic field. The study shows that the spin transitions of ceramic Eu&lt;sup&gt;3+&lt;/sup&gt;:Y&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt; have coherence properties comparable to the best rare-earth-doped materials available.&lt;/p&gt;

&lt;p&gt;These results have been highlighted in JPhys+, news and views from the Journal of Physics series (IOP): https://jphysplus.iop.org/2017/02/09/long-spin-coherence-lifetime-in-eu3y2o3-ceramic/&lt;/p&gt;
