We present a systematic study of the crystal field interactions in theLi$R$F$_4$, $R$ = Gd, Ho, Er, Tm and Yb, family of rare-earth magnets. Usingdetailed inelastic neutron scattering measurements we have been able toquantify the transition energies and wavefunctions for each system. This allowsus to quantitatively describe the high-temperature susceptibility measurementsfor the series of materials and make predictions based on a mean-field approachfor the low-temperature thermal and quantum phase transitions. We show thatcoupling between crystal field and phonon states leads to lineshape broadeningin LiTmF$_4$ and level splitting in LiYbF$_4$. Furthermore, using highresolution neutron scattering from LiHoF$_4$, we find anomalous broadening ofcrystal-field excitations which we attribute to magnetoelastic coupling.
