Angular dependence of Fe" ESR spectra in hex?tgonal Basic. has been measuredaround the ferroelectric phase transition temperature of 66 K (7=.). The principal axesof crystal field tensor rotate in the v#-plane with decreasing the temperature from T.to 51 K. The rotation angle becomes 30' at 51 K and the axes c.lo not rotate below 51K. Analysis due to the superposition model indicates that shear strain zv... appears inthe act-plane between T. and 51 K, and the symmetry becomes monoclinic 2.h-BaTiO., ferroelectric phase transition, ESR, superposition model
