If you missed the online webinar or want to refresh your memory - don't worry. The whole webinar is now available on YouTube with the title "Broadband Ferromagnetic Resonance: CryoFMR".
Register for Quantum Design's upcoming free webinar devoted to our Broadband Ferromagnetic Resonance capabilities for the PPMS product line!
This webinar will focus on the CryoFMR capabilities for the PPMS product line. However, the instruments provided by NanOsc Instruments can be used in a variety of systems. Near the end of the webinar Randy Dumas will describe briefly some of these other platforms. Regardless of platform, the basics behind the CryoFMR/PhaseFMR options and software essentially remain unchanged.

Our distributor Quantum Design has issued an Application Note that describes how to use a our new dedicated ISHE CPW suitable for the CryoFMR probe available for the PPMS/DynaCool/VersaLab platforms.
If we consider a ferromagnet/non-magnetic bilayer (e.g. Ni80Fe20/Pd) undergoing FMR, a diffusive flow of spin from the Ni80Fe20 ferromagnet will enter the non-magnetic Pd layer due to a phenomenon known as spin pumping. Then, via the inverse spin Hall effect (ISHE), which can be significant in non-magnetic layers with a large spin-orbit interaction (e.g. Pt, W, Pd, etc.), this diffusive flow of spins will be converted into a measurable transverse DC voltage. Our new CPW integrates electrical contacts for measuring this ISHE generated voltage and are via the standard sample chamber wiring connected to a separate input on the CryoFMR spectrometer. The ISHE voltage is measured using the same lock-in amplifier used to measure the FMR response.
At the INTERMAG conference in Singapore NanOsc Instruments introduced its new compact set of insert and wave guides for the MPMS 3. This adds yet another cryostat to the range of supported systems for broadband FMR analysis with varying temperature using the CryoFMR spectrometers.
Broadband FMR spectroscopy allows for measurements continuously spanning several 10’s of GHz. Measurements over a wide frequency range allow for significant improvements in accurately extracting a variety of material parameters not accessible by static measurement techniques.
Broadband FMR is particularly well-suited for studying magnetic thin films, which not only form the backbone of fundamental spintronics and magnonics research but are also constituents of current and future technologies focused on magnetic memories, sensors, logic, and microwave signal processing.
NanOsc Instruments displayed the latest additions to its product line of broadband FMR spectrometers, the PhaseFMR-8 for room temperature measurements, and the CryoFMR-8 for variable temperature measurements. These entry level FMR spectrometers with advanced analysis capabilities are excellent for physics education and materials research. The easy to use software provides Lorentzian curve fitting and parameter extraction for both in-plane and out-of-plane analysis of thin films giving the gyromagnetic ratio, saturation magnetization, damping, inhomogeneous broadening, and anisotropy.
Our world-wide distributor Quantum Design, Inc. has installed the first PhaseFMR in India.
We make FMR easy with a very user-friendly software that controls the measurements and extracts important static and dynamic magnetic properties through Kittel function fitting and damping analysis.
The first CryoFMR for China is shipped out. This spectrometer will be used with a Quantum Design Versalab cryostat to provide fast, easy-to-use, and reliable FMR measurements down to 50 K.
