Abstract
A device includes a magnetic layer and a guiding structure arranged over the magnetic layer and configured to sequentially transfer a skyrmion in the magnetic layer along a transfer pattern in response to a rotating magnetic field. The device further includes a plurality of magnetoresistive elements arranged along the transfer pattern and configured to detect a position of the skyrmion in the transfer pattern. The device is configured to determine a number of rotations of the rotating magnetic field based on the detected position of the skyrmion in the transfer pattern.

A device, comprising:
- a magnetic layer;
- a guiding structure arranged over the magnetic layer and configured to sequentially transfer a skyrmion in the magnetic layer along a transfer pattern in response to a rotating magnetic field;
- and
- a plurality of magnetoresistive elements arranged along the transfer pattern and configured to detect a position of the skyrmion in the transfer pattern,
- wherein the device is configured to determine a number of rotations of the rotating magnetic field based on the position of the skyrmion in the transfer pattern.
A method for fabricating a device, wherein the method comprises:
- providing a magnetic layer;
- arranging a guiding structure over the magnetic layer, wherein the guiding structure is configured to sequentially transfer a skyrmion in the magnetic layer along a transfer pattern in response to a rotating magnetic field;
- and
- arranging a plurality of magnetoresistive elements along the transfer pattern, wherein the magnetoresistive elements are configured to detect a position of the skyrmion in the transfer pattern,
- wherein the fabricated device is configured to determine a number of rotations of the rotating magnetic field based on the position of the skyrmion in the transfer pattern.
