Query: Skyrmions in an oblique field: A path to novel binary and quaternary
  memory   We propose a novel binary and quaternary memory device based upon skyrmion
states induced by the oblique field in a square magnetic island. To describe
stable states and dynamics of the skyrmion, we employ the lattice model that
uses the parameters of a real material and accounts for all relevant
interactions. Depending on the orientation of the field, two or four spatially
separated energy minima emerge in the oblique field. The energy barriers
between the minima can be controlled by the strength and orientation of the
magnetic field. We study the dynamics of the skyrmion and show that it can be
moved between any two states by application of the field gradient. Islands of
thickness of a few tens of atomic layers permit room-temperature manipulation
of the proposed device.
