Broadband Ferromagnetic Resonance Spectrometer for Temperature- dependent Magnetization Dynamics in Spintronic Heterointerfaces
Abstract
The equipment purchase established a versatile ferromagnetic resonance (FMR) spectrometer for studies of static and dynamic magnetization in thin film heterointerfaces used in high-frequency spintronics and other magnetic devices. This spectrometer will allow measurements of FMR, spin torque FMR and FMR driven inverse spin Hall effect (ISHE) over a wide range of frequencies (1 to 32 GHz), temperature (1.5 K to 300 K) and magnetic field (Hdc, 0 to 5 tesla). The proposed instrument will have interchangeable GHz probes to enable measurements in two Hdc configurations: one parallel to sample plane and other perpendicular to it. These probes will be equipped with additional features to allow electrostatic and thermal gating to stimulate magnetization dynamics. This facility significantly enhances the capability of the ambient-temperature FMR spectrometer that has been built in the last one year under the ongoing AFOSR funded project on magnetic thin film nanostructures for radio frequency electronics.
