• Angular dependence of Fe" ESR spectra in hexagonal Basic, has been measuredaround the phase transition temperature of 222 K (7'.). The HSR lines split in threelines respectively in the aZ>-plane below T., and tlne intensities change with uniaxialstress. These splittings can be explained by the formation of domains. The spinHamiltonian parameters D and a are -0.059 cm ' and 0.005 cm ', respectively, inthe both phases. The parameter E is nearly zero above 221 K and increases withdecreasing the temperature. The principal axis Z rotates in the Z>c-plane below T..Analysis due to the superposition model indicates that Fe" substitutes for Ti site inTi.Og cluster and shifts along the Z>-axis with decreasing the temperature below T..
