Anomalous behaviour of the photoacoustic signal near the phase transition in the thallium blue bronze(Tl 0.3MoO 3)
Temperature dependence of the photoacoustic(PA) spectra of the thallium blue bronze near the phase transition was first measured. The anomalous behaviors of the PA amplitude and phase angle, and a peak of the specific heat and thermal conductivity (C S(T)·K S(T)) in the vicinity of 180K were observe...

Summary: | Temperature dependence of the photoacoustic(PA) spectra of the thallium blue bronze near the phase transition was first measured. The anomalous behaviors of the PA amplitude and phase angle, and a peak of the specific heat and thermal conductivity (C
S(T)·K
S(T)) in the vicinity of 180K were observed, and qualitatively provided evidence that the phase transition is a second-order phase transition in agreement with the specific heat. |
