Abstracts

EN

Spin wave modes in antiferromagnetically exchange-coupled magnetic double layers are analyzed theoretically. The considered structure is assumed to be covered by a nonmagnetic metallic layer. The spin wave frequencies and spin wave life times are determined from the macroscopic description based on the Landau-Lifshitz-Gilbert equation, which includes the torque due to spin pumping to the cap layer.
