“Purchasing the CryoFMR system has enabled our group to branch out into spin wave measurements quickly and easily. Without prior experience running microwave/FMR measurements, the CryoFMR has allowed us to get a spin-wave research programme up and running with several resulting publications in a short period of time.

In addition to conventional thin-film measurements, the sensitivity of the CryoFMR has also allowed us to measure nanostructures – something which we’d previously struggled with using other experimental setups.

The technical support team are responsive and have continued to update the control software and add additional features. The system has been low-maintenance, easy to operate and I’d happily recommend it, especially to existing PPMS or MPMS owners.”
