The ST-FMR product line
NanOsc Instruments offers two spectrometers, PhaseFMR-20ST and PhaseFMR-40ST, that expand our well established and time tested broadband FMR capabilities into the emerging area of spin torque ferromagnetic resonance (ST-FMR) measurements and analyses.
Broadband ST-FMR opens for analysis of spin−orbit torques (SOTs) typically observed in ferromagnetic/heavy metal (FM/HM) structures. Such analysis has attracted a growing attention in various application fields, for example SOT-based magnetic random access memories (MRAMs) and SOT-based spin Hall nano-oscillators (SHNOs) for on-chip microwave wireless communication and neuromorphic computing.

Key Features:
- Turn-key combined FMR and ST-FMR spectrometers with easy to use software interface
- Built-in RF source, bias current source, bias-tee, detectors and lock-in
- Micro manipulator with a ground-signal-ground probe to make electrical contact with a device on a sample
- Calculate the Effective magnetization (Meff), anisotropy (K), gyromagnetic ratio (γ), damping (α), inhomogeneous broadening (ΔHo)
- ST-FMR adds extraction of spin Hall angle (SHA), damping-like and field-like torque efficiency (DLTE and FLTE)
