Snapshots During Spin Wave Excitation Before Vortex Core Reversal The

Snapshots During Spin Wave Excitation Before Vortex Core Reversal The Here we present experiments which verify that polarization selective vortex core reversal can indeed be achieved by spin wave excitation with in plane rotating ghz magnetic fields. By tuning the nanowire length, the excitation frequency, the microwave pulse duration, and the spin current value, we show that the optimum (low power) manipulation of the bp dw can be achieved.

Solution Magnetic Vortex Core Reversal By Excitation Of Spin Waves Our analysis allows us to explain the experimentally observed switching diagram for simultaneous excitation of spin waves and gyrotropic mode. in this letter we address spin wave dynamics involved in fast and selective vortex core polarity reversal by rotating magnetic field bursts. The first experimental obser vation of spin wave mediated vortex core reversal was published recently by applying bursts of relatively long rotating magnetic fields with a duration of 24 periods [29]. Here we report on the controlled manipulation of the vortex core polarization by excitation with small bursts of an alternating magnetic field. Here, we apply time resolved scanning transmission x ray microscopy (tr stxm) to demonstrate that magnetic vortex cores under the influence of a static magnetic bias field can be used as such manipulable spin wave emitters.

We experimentally demonstrate that unidirectional reversal of the magnetic vortex core polarity is possible by excitation with sub 100 ps long orthogonal monopolar magnetic pulse sequences in a wide range of pulse lengths and amplitudes. Here we show experimentally that unidirectional magnetic vortex core reversal is possible by direct excitation of the magneto static spin wave eigenmodes. the results are confirmed by micromagenetic simulations, which clearly show the selection rules for this reversal mechanism. Here we present experiments which verify that polarization selective vortex core reversal can indeed be achieved by spin wave excitation with in plane rotating ghz magnetic fields.
