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.

散射近场显微镜，用于 100 GHz 至 3 THz 光谱范围内的高空间分辨率和时间相关傅里叶变换光谱，用于研究约 10 nm 长度范围内反铁磁薄膜中磁输运的电、热和光学效应。重点是反铁磁纳米结构的激发、动力学和新颖的切换过程。柏林-阿德勒斯霍夫 PTB 威利-维恩实验室的低能量存储环“计量光源”(MLS) 的同步加速器辐射被用作 FT-SNOM 连续红外和太赫兹光谱范围内的强大辐射源。
