Abstract
We present the full magnetic tensors of the and electronic states for both crystallographic sites in :, deduced through the use of Raman heterodyne spectroscopy performed along nine different crystallographic directions. The maximum principle values were determined to be 0.447 (site 1) and 0.523 (site 2) for the ground state and 2.490 (site 1) and 3.319 (site 2) for the excited state. The determination of these tensors provide essential spin Hamiltonian parameters that can be utilized in future magnetic and hyperfine studies of :, with applications in quantum information storage and communication devices.
