Abstract

We study the magnetoresistance properties of thin ferromagnetic CrO ₂ and Fe₃O₄ films under microwave irradiation. Both the sheet resistance ρ and the Hall voltage V_Hall characteristically change when a ferromagnetic resonance (FMR) occurs in the film. The electrically detected ferromagnetic resonance (EDFMR) signals closely match the conventional FMR, measured simultaneously, in both resonance fields and line shapes. The sign and the magnitude of the resonant changes Δ_ρ/ρ and ΔV_Hall/V_Hall can be consistently described in terms of a Joule heating effect. Bolometric EDFMR thus is a powerful tool for the investigation of magnetic anisotropy and magnetoresistive phenomena in ferromagnetic micro- or nanostructures.
