AN INVESTIGATION OF EPR PARAMETERS AND K + VACANCY IN KMgF 3 :Cr 3+

It has been shown that the paramagnetic ions doped in KMgF 3 are in axial symme-try environment. In the present work, that the shift of the nearest neighbour F - ions of the K + vacancy, 3.76°and -0.64°deviating from the c 3 axis respectively, are predic-ted by analysing the anisotropic g factors and the zero-field splitting of EPR.
