In the resistive phase transition in VO 2 , temperature excursions taken from points on the major hysteresis loop produce minor loops. For sufficiently small excursions these minor loops degenerate into single-valued, nonhysteretic branches NHBs linear in log versus T and having essentially the same or even higher temperature coefficient of resistance TCR as the semiconducting phase at room temperature. We explain this behavior based on the microscopic picture of percolating phases. Similar…
