我们提出了高精度的比热测量附近的结构转变SrTi${\mathrm{O}}_{3}$。我们没有检测到临界行为,但只有一个跳跃,后面跟着一个尾巴。这可以直接从靠近$R$角的声子色散曲线中计算出来,在那里${\ensuremath{\Gamma}}_{25}$模变软。
We present high-precision measurements of the specific heat near the structural transition of SrTi${\mathrm{O}}_{3}$. We did not detect critical behavior, but only a jump followed by a tail. This can be calculated directly from the phonon dispersion curves near the $R$ corner, where the ${\ensuremath{\Gamma}}_{25}$ mode becomes soft.
