No clear excitations could be identified, possibly due to challenging experimental conditions ultimately leading to mechanical failure of the sample environment. Characteristic excitations from a Rollin film of superfluid helium were observed, as the weakest signal yet identified at the CAMEA SINQ instrument.Neutron scatteringMagnetic materialsSpin excitationsSrCu2(BO3)2SCBOSuperfluid heliumstudent work::semester or other student projects
