  Using the recently developed method we calculate the crystal field parameters
in yttrium and lutetium aluminum garnets doped with seven trivalent Kramers
rare-earth ions. We then insert calculated parameters into the atomic-like
Hamiltonian taking into account the electron-electron, spin-orbit and Zeeman
interactions and determine the multiplet splitting by the crystal field as well
as magnetic $\hat{g}$ tensors. We compare calculated results with available
experimental data.
