Abstract
EPR spectra of Cr+3 and Fe+3 in LiKSO4 (single crystal and powder samples) were studied as a function of temperature in the range—;195°C ⟷ 20°C. Spin Hamiltonian parameters were determined at—195°C and 20°C. The implications of these results on the crystal structure of LiKSO4 at these temperatures are fully discussed.
