Misfit Strain in Superlattices Controlling the Electron-Lattice Interaction via Microstrain in Active Layers

Figure 3

The magnetic phase diagram of cuprates: 𝑇_𝑐, doping 𝛿 and misfit strain 𝜂. 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 (𝛿_𝑐,𝜂_𝑐), where the commensurate magnetic stripe phase occurs at 𝛿 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.
