(a) An example of the resistivity inflection point TN derived from () on the insulating side of the strain (ε>0). (b) The thermal hysteresis coercivity versus strain. (c) Conductivity derivatives for ε=+0.3% versus temperature. Temperature-dependent resistivity derivatives (open circle) with respect to the temperature power-law function with the power index α equal to, from top to bottom, 4/3 (blue), 3/2 (green), 5/3 (red) and 2 (black) for ε=−0.3% (d), −1.2% (e) and −2.9% (f). Dash lines are guides for eyes. For ε=−2.9%, triangles are used to indicate the temperature region where the derivative may be considered as a constant within the noise.
