Abstract

We performed an inelastic neutron scattering experiment to study the magnetic excitation of O₂ molecules adsorbed in a microporous compound. A dispersionless excitation with characteristic intensity modulation is observed at ℏω = 7.8 meV at low temperature. The neutron cross section is explained by using a spin dimer model with an intradimer distance of 3.1 Å. Anomalous behaviour in the temperature dependence is discussed in the context of enhanced magnetoelasticity in the soft framework of the O ₂ molecule.
