摘要：

Electron paramagnetic resonance of Fe3+ gives evidence for a phase-transition-like feature in SrTiO3 below T(q) = 37 +/- 1 K, both in the tetragonal and the pressure-induced trigonal phase. In the latter, T(q) shifts to lower temperatures as a function of uniaxial stress p111. The new phenomenon is very tentatively discussed in terms of a possible transition to a novel coherent quantum state.
