Query: Nanosecond-timescale low error switching of in-plane magnetic tunnel
  junctions through dynamic Oersted-field assisted spin-Hall effect   We investigate fast-pulse switching of in-plane-magnetized magnetic tunnel
junctions (MTJs) within 3-terminal devices in which spin-transfer torque is
applied to the MTJ by the giant spin Hall effect. We measure reliable
switching, with write error rates down to $10^{-5}$, using current pulses as
short as just 2 ns in duration. This represents the fastest reliable switching
reported to date for any spin-torque-driven magnetic memory geometry, and
corresponds to a characteristic time scale that is significantly shorter than
predicted possible within a macrospin model for in-plane MTJs subject to
thermal fluctuations at room temperature. Using micromagnetic simulations, we
show that in the 3-terminal spin-Hall devices the Oersted magnetic field
generated by the pulse current strongly modifies the magnetic dynamics excited
by the spin-Hall torque, enabling this unanticipated performance improvement.
Our results suggest that in-plane MTJs controlled by Oersted-field-assisted
spin-Hall torque are a promising candidate for both cache memory applications
requiring high speed and for cryogenic memories requiring low write energies.
