Temperature-Driven Spin Reorientation Transition in CoPt/AlN Multilayer Films

Figure 3

Magnetic anisotropy energy 𝐾 e versus temperature for CoPt/AlN multilayer films with the CoPt layer thickness as 2, 4, 6, and 8 nm. 𝐾 e > 0 and 𝐾 e < 0 correspond to perpendicular and in-plane magnetic anisotropy, respectively.
