我们提供的实验证据表明,在有限温度、宏观尺寸和没有磁场的情况下,Cu (100) 上的 1 个单层 Co 存在长程铁磁有序。磁化强度作为所施加磁场的函数遵循磁滞回线。在剩磁(零施加磁场)下,薄膜处于单畴状态。通过将薄膜分解成磁域来发生磁化反转。
We give experimental evidence that long-range ferromagnetic order exists at finite temperatures, over a macroscopic size and in the absence of magnetic field for 1 monolayer of Co on Cu (100). The magnetization as a function of the applied magnetic field follows an hysteresis loop. At remanence (zero-applied magnetic field) the film is in a single-domain state. The magnetization reversal occurs by breaking down of the film into magnetic domains.
