“…Some indications of the thermoelastic martensitic effect importance in the M-I transition in V 2 O 3 have been reported using acoustic emission measurements [27]. We propose that in the particular case of V 2 O 3 films, substrate enables a releasing of the strain by inducing a heterogeneous state, as it is the case in a martensitic scenario, where a large number of small domains increases the spread in transition temperature of each domain [28]. CONCLUSION We have presented a detailed study of thermal hysteresis present in the transport properties of V 2 O 3 thin films.…”

The thermal hysteresis of the electronic transport properties were studied for V2O3 thin films. The temporal evolution of the resistance shows the out-of-equilibrium nature of this hysteresis with a very slow relaxation. Partial cycles reveal not only a behavior consistent with phase coexistence, but also the presence of spinodal temperatures which are largely separated. The temperature spreading of phase coexistence is consistent with the bulk phase diagram in the pressure-temperature plane, confirming that the film is effectively under an effective pressure induced by the substrate.

“…But after a few tens of thermal cycles, the resistance stabilized to a reproducible history-independent value at 300 K. The measurements reported here were all performed on such 'trained' samples. This phenomenon is well known for materials undergoing martensitic transitions and is likely to be due to the formation of microcracks [64].…”

Kinetic Spinodal Instabilities in the Mott Transition inV2O3: Evidence from Hysteresis Scaling and Dissipative Phase Ordering

We present the first systematic observation of scaling of thermal hysteresis with the temperature scanning rate around an abrupt thermodynamic transition in correlated electron systems. We show that the depth of supercooling and superheating in vanadium sesquioxide (V_{2}O_{3}) shifts with the temperature quench rates. The dynamic scaling exponent is close to the mean field prediction of 2/3. These observations, combined with the purely dissipative continuous ordering seen in "quench-and-hold" experiments, indicate departures from classical nucleation theory toward a barrier-free phase ordering associated with critical dynamics. Observation of critical-like features and scaling in a thermally induced abrupt phase transition suggests that the presence of a spinodal-like instability is not just an artifact of the mean field theories but can also exist in the transformation kinetics of real systems, surviving fluctuations.

“…Crystalline distortion at phase transition in VO 2 [2,8] is the reason of instability. Distortion accompanied by a discontinuous volume change [9] generates the mechanical stresses which lead to the formation of microcracks [7,10]. The microcracks produce the irreversible change in the properties of VO 2 single crystals and VO 2 -based materials.…”
