|Abstract:||The angular variation of V4+ electron paramagnetic resonance (EPR) line positions were recorded in single crystals of β-Mg2V2O7 and α-Zn2V2O7 at 120 K and 295 K in three mutually perpendicular planes in the temperature range from 120 to 295 K and at some intermediate temperatures. Least-squares fitting was used by diagonalization of the Spin-Hamiltonian (SH) matrix to determine the SH parameters and the orientations of the principal axes of the g- and A-matrices from the angular variations of the EPR line positions. Although the V4+ SH parameters were found to be similar in the two crystals, the orientations of the principal axes of the g- and A-matrices were not found to be coincident in the two crystals.
