摘要：
Coupled gyration modes of the magnetic vortices are studied in two separated disks. We have experimentally detected that all four modes are selectively excited mainly by the spin-transfer torque, depending on the combination of their polarities and chiralities. The evaluated dipolar coupling intensity shows a certain decrease from the rigid vortex model.
