Figure 3: The magnetic phase diagram of cuprates: , doping and misfit strain . The The misfit strain η (i.e., microstrain or internal chemical pressure) and the doping δ are normalized to the critical values of the 1/8 phase , where the commensurate magnetic stripe phase occurs at doping of 1/8 hole for Cu site and misfit strain 7%. Therefore the Aeppli–Bianconi critical point is near the point (1, 1) in the 2D space.
