Recently, the first Cyro-FMR device in China was successfully installed at Prof. Pan Liqing of the Three Gorges University. Ferro-Resonators can accurately measure magnetic fields. Professor Pan Liqing mainly engaged in magnetic physics, low-dimensional physics and related functional materials based on the application of research, published over 100 papers, of which SCI papers included more than 70 articles, SCI papers cited more than 300 times to declare China's invention patents 13 (authorized 9) and utility model patents 2 (have been authorized 2). The installation of this Cyro-FMR device will continue to help Prof. Pan Liqing's research. Ferromagnetism resonance (FMR) is a phenomenon of using magnetic substance to absorb energy strongly from the microwave magnetic field. It is an important experimental method to study the macroscopic properties and microstructure of materials. In the magnetic nanostructures, a variety of spin-wave modes may play a dominant role, so complete mastery of these modes is critical to the final device design and stability. Ferromagnetic resonators make accurate measurements of these modes as a function of magnetic field. Sweden NanOsc Instruments AB and Quantum Design USA continue to explore, based on the conventional FMR constantly updated exploration, developed with the Montana thermostat and PPMS and VersaLab temperature-variable Cyro-FMR used to achieve high precision and plug and play . The system not only provides all the hardware for microwave generation and detection, but also comes with measurement and analysis software that easily meets the customer's testing needs. This Pan professor's group is installed this variable temperature Cryo-FMR, we wish Professor Pan's research on the basis of this higher level.
