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

Figure 1

In-plane and out-of-plane Magnetization-Temperature (𝑀-𝑇) curves of CoPt/AlN multilayer films with the CoPt layer thickness of 2, 4, 6 and 8 nm for (a), (b), (c), and (d), respectively. The inset image in (a) is the in-plane 𝑀-𝑇 curve in a small magnetization range. In (b) the corresponding magnetization states are illustrated.
