Analysis of inelastic neutron scattering data recorded for the rare earth intermetallic compound TmV₂Al₂₀ yields a cubic crystal field Hamiltonian with parameters x = −0.63(1) and W = +0.43(1) K (Lea, Leask & Wolf notation). This result is supported by a strong electron paramagnetic resonance signal that is consistent with magnetic splitting of the first excited (Γ₅⁽¹⁾) state. Using this crystal field Hamiltonian, single crystal magnetisation and specific heat data are then interpreted in terms of a model that involves partial Al flux substitution of an approximately 10% depleted Tm “cage” site.
