Scattering near-field microscope for high spatially resolved and temporally correlated Fourier transformation spectroscopy in the spectral range from 100 GHz to 3 THz to study electrical, thermal and optical effects of magnetotransport in antiferromagnetic thin films on a length scale of about ~10 nm. The focus is on excitation, dynamics and novel switching processes of antiferromagnetic nanostructures. The synchrotron radiation of the low energy storage ring "Metrology Light Source" (MLS) at the Willy-Wien-Laboratorium of PTB in Berlin-Adlershof is used as a powerful radiation source in the continuous infrared and terahertz spectral range for the FT-SNOM.

利用100 GHz ~ 3 THz高空间分辨、时间相关的傅里叶变换光谱散射近场显微镜，研究了长度约为~10 nm的反铁磁薄膜中磁输运的电学、热学和光学效应。重点研究了反铁磁纳米结构的激励、动力学和新型开关过程。柏林-阿德勒肖夫PTB威利-维恩实验室的低能量存储环“计量光源”（MLS）的同步辐射被用作FT-SNOM连续红外和太赫兹光谱范围内的强大辐射源。
