NanOsc CryoFMR FMR Spectrometer

Coplanar Waveguide Ferromagnetic Resonance

The CryoFMR is a FMR spectrometer from NanoOsc. When combined with the Cryostation C2 system and Magneto-Optic module, it can be used as a turn-key variable temperature Coplanar Waveguide Ferromagnetic Resonance (CPW-FMR) spectrometer. CPW-FMR is a spectroscopic technique that measures the coupling between an RF signal traveling in a coplanar waveguide and the oscillating magnetisation of a sample.  

In turn, this can be used to determine the saturation magnetisation (Ms) or the gyromagnetic ratio (λ), in addition to parameters of the dynamic behaviour of the spin excitation, such as the intrinsic damping (α) and the inhomogeneous line broadening (ΔHo).

No Vector Network Analyser is required as the system uses an AC a lock-in technique.
