Abstract

Hole burning, which is attributed to optical pumping of nuclear-quadrupole levels, has been observed in the stoichiometric rare-earth compound, EuP₅O₁₄. The long lifetime of these holes (∼60 min) implies slow nuclear-spin flip-flop rates. The small magnetic moment of Eu³⁺ has prevented conventional magnetic-resonance measurements on Eu³⁺ compounds, but hole burning provides a sensitive method for the optical detection of nuclear-magnetic resonance and nuclear-quadrupole resonance. We have used hole burning and optically detected nuclear-quadrupole resonance to determine quadrupole splittings in the ground (⁷F₀) and excited (⁵D₀) states.
