Fluctuations and Correlations in SrTiO3forT>~Tc

The linewidth broadening of the paramagnetic resonance of the ${\mathrm{Fe}}^{3+}-V_{\mathrm{O}}$ center in SrTi${\mathrm{O}}_3$ near $T_c$ has been measured accurately and analyzed for $T\to {T_c}^{+}$. It is found that the order-parameter susceptibility $\chi (\overrightarrow{\mathrm{q}},T)$ is two-dimensionally anisotropic with an anisotropy parameter $\Delta =\frac{1}{60}$. The critical exponent of the correlation length $\xi$ is found to be $\nu =0.63\mathrm{}\pm 0.07$. The EPR linewidth is cusp shaped for $T\to {T_c}^{+}$ and finite at $T=T_c$.
