论文摘要
我们提出了一个紧凑型\ textIt {intu}电磁系统，该电磁系统具有活跃的冷却系统，用于在超高真空环境中。主动冷却增强了热稳定性，并增加了可以通过线圈应用的电流，从而促进了在实时沉积实验中应用所需的均匀磁场的产生。电磁体已被整合到反射率差磁磁光（RD-MOKE）光谱系统中，该光谱系统允许对光学各向异性的同步测量和极性moke几何形状中的磁化响应。 Proof of principle studies have been performed in real-time during the deposition of ultra-thin Ni films on Cu(110)-(2$\times$1)O surfaces, corroborating the extremely sharp spin reorientation transition above a critical coverage of 9 monolayers and demonstrating the potential of the applied setup for real-time and \textit{in-situ} investigations of magnetic thin films and interfaces.
We present a compact \textit{in-situ} electromagnet with an active cooling system for the use in ultra-high vacuum environments. The active cooling enhances the thermal stability and increases the electric current that can be applied through the coil, promoting the generation of homogeneous magnetic fields, required for applications in real-time deposition experiments. The electromagnet has been integrated into a reflectance difference magneto-optic Kerr effect (RD-MOKE) spectroscopy system that allows the synchronous measurement of the optical anisotropy and the magneto-optic response in polar MOKE geometry. Proof of principle studies have been performed in real-time during the deposition of ultra-thin Ni films on Cu(110)-(2$\times$1)O surfaces, corroborating the extremely sharp spin reorientation transition above a critical coverage of 9 monolayers and demonstrating the potential of the applied setup for real-time and \textit{in-situ} investigations of magnetic thin films and interfaces.
