Abstract

We propose a method of measuring the L-band microwave. An in-plane magnetized permalloy thin strip is selected as a passive sensor in an external magnetic field. By analyzing the sensor´s L-band microwave-induced direct current response in field-swept mode, the polarization of microwave magnetic component and the relative phase can be obtained simultaneously in terms of magnetization dynamics, demagnetization effect and magnetic anisotropy.
