Specific heat measurements of SrTiO3 near 110 K

The structural phase transition in under uniaxial stress in the [110] direction: a calorimetric study

“…At 105.0 K the specific heat shows a stepwise behaviour. Its specific heat jump c 0 is estimated to be 0.003 J g −1 K −1 which is in reasonable agreement with the values obtained by Garnier [16] and Franke and Hegenbarth [17]. Within the experimental resolution, c 0 remains constant for all applied stresses while the transition width increases with increasing stress.…”

“…Such experiments are rather difficult to conduct because the device for the application of stress disturbs the heat conduction in the sample, producing uncontrolled heat losses. Although the excess specific heat without stress has been measured by several authors [14,15,16,17], there was only one study in which stress was applied to the sample [18]. No quantitative evaluation of the stress was possible from those experimental results.…”

Revisiting the fascinating properties of EuTiO 3 and its mixed crystals with SrTiO 3 : Possible candidates for novel functionalities

“…An anomaly similar in shape and magnitude [14] to that found for the corresponding transition in STO (see inset b) in Fig. 8 [37][38][39][40][41] is seen at 282(1) K. This value is close to the theoretically expected phase transition temperature and in agreement with X-ray powder diffraction studies, see above. In addition, the transition to the AFM state is evident in the specific heat data as a λ-type anomaly at low temperature (see inset a) in Fig.…”

Phase transitions in BaMnF4

“…McCorinick at Texas finds that any specific heat anomaly at TO is much less than 1% of the background value. This is reasonable in comparison with the magnitude measured for the second-order structural transition in SrTiOs (Franke and Hegenborth 1974). However, E J Ryder et al (1969) reports a measurable specific heat anomaly at To in unpublished work cited by Keve et a1 (1969).…”
