Spintronic Detector of Linearly Polarized Microwave Radiation Based on a Ferromagnet/Normal Metal Heterostructure
The effect of the polarization of microwave radiation on the efficiency of ferromagnetic resonance excitation and spin pumping from a ferromagnetic lutetium garnet Lu3Fe5O12 thin film into normal metal Pt has been studied. The voltages created due to the inverse spin Hall effect in a Pt layer have been measured when the polarization of the exciting electromagnetic wave changed from linear to circular. It has been experimentally established and theoretically confirmed that the electromagnetic radiation component perpendicular to the static magnetization direction determines the nonzero potential difference created in the normal metal layer. The considered “ferromagnet–normal metal” heterostructure can be used as a tunable resonant detector of polarized microwave radiation and as polarization filters. The data on the practical application of Lu3Fe5O12/Pt are extremely relevant for modern telecommunications.
