Overview

Experimental study observes direct current voltage during ferromagnetic resonance in magnetic trilayers, suggesting evidence of the spin-pumping effect.

Key Points

Investigate direct current voltage generation during uniform magnetization precession in ferromagnetic trilayers to evaluate its connection to the spin-pumping effect.
Excited the uniform mode of magnetization precession using microwave incident power under ferromagnetic resonance conditions.
Measured generated direct current voltages across ferromagnetic/normal-metal/ferromagnetic trilayers while varying spacer-layer materials, spacer thickness, and microwave power.
Direct current voltage appeared in-plane across the trilayers simultaneously with the excitation of uniform magnetization precession.
Generated voltage scaled with microwave incident power and depended strongly on the thickness and chemical composition of the normal-metal spacer.
Observed voltage characteristics qualitatively support predictions of the spin-pumping effect.
