Optical spectroscopy of single- and two-ion transitions in an antiferromagnetic stoichiometric rare-earth crystal
Masaya Hiraishi, Gabrielle A. Hunter-Smith, Gavin G. G. King +5
We characterise optical transitions of neodymium ions (Nd3+) in antiferromagnetic neodymium gallate (NdGaO3) with applied fields up to 3 T. The magnetic phase of this material has…

Long optical coherence times and coherent rare earth-magnon coupling in a rare earth doped anti-ferromagnet
Masaya Hiraishi, Zachary H. Roberts, Gavin G. G. King +2
Rare-earth ions are characterised by transitions with very narrow linewidths even in solid state crystals. Exceedingly long coherence times have been shown on both spin and optical…
