Supplementary Movie 4 Reversible pressure- and current-induced phase transition. This movie shows the pressure-induced phase transition from λ-Ti3O5 to β-Ti3O5 and current-induced phase transition from β-Ti3O5 to λ-Ti3O5. The initial part of this movie displays the pressure-induced phase transition from λ-Ti3O5 to β-Ti3O5, where the accumulated heat energy in λ-Ti3O5 is released (energy release process). Next, electric current is flowed to the pressure-produced β-Ti3O5 and β-Ti3O5 transforms to λ-Ti3O5, i.e., current-induced phase transition accompanying accumulation of heat energy (heat storage process). The release and accumulation of heat energy are caused repeatedly by alternating pressure application and current flow.
