Fe3+的电子顺磁共振证明了SrTiO3在T(q) = 37 +/- 1 K以下，在四方相和压力诱导的三角相中都有类似相变的特征。在后者中，T(q)作为单轴应力p111的函数向较低温度移动。这一新现象是非常试探性地讨论了可能过渡到一个新的相干量子态。
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.
