This system is for the magnetic materials, especially the best for the research such as Spintoronics and Quantum dots technology, with following features. • It has the measurement sensitivity more than that of standard type X band ESR system, because it uses ferromagnetic resonance(FMR). • You can rotate the specimen by two axis accurately, and can incline the specimen. • You can change the static magnetic field from zero to high magnetic field up to 500 mT.
