The PhaseFMR product line

If you want to do broadband FMR analysis at room temperature with a dipole electromagnet then this is the product line for you. Broadband FMR is performed using a coplanar waveguide. Four PhaseFMR models cover different frequency ranges, all starting at 2 GHz.

The ferromagnetic resonance (FMR) of a magnetic thin film is a fundamental property for any high-frequency magnetic and spintronic application, such as hard drive read-heads, MRAM, spin torque MRAM, and spin torque oscillators. PhaseFMR measures the ferromagnetic resonance at different applied magnetic fields and its analysis software extracts:
  • Saturation magnetization (Ms)
  • Gyromagnetic ratio (γ/2π)
  • Anisotropy (Hk)
  • Intrinsic damping (α)
  • Inhomogeneous broadening (ΔH)
Its measurements also enable the user to extract the exchange stiffness (A) and inverse spin Hall effect (ISHE) with an optional dedicated CPW.

There are integration kits and CPW holders available for generic dipole magnets as well as for the MicroSense EZ VSM series and the MCS-EMP and 8600 Series VSM systems from Lake Shore Cryotronics.
