Electric-field-induced thermally assisted switching of monodomain magnetic bits
We present a study of the electric-field-induced switching of magnetic memory bits exhibiting interfacial voltage-controlled magnetic anisotropy (VCMA). Switching is analyzed in the single-domain approximation and in the thermally activated regime. The effects of external magnetic fields, magnitudes of the perpendicular anisotropy and VCMA effect, and voltage pulse width on the switching voltag...
متن کاملSwitching dynamics in titanium dioxide memristive devices
Memristive devices are promising components for nanoelectronics with applications in nonvolatile memory and storage, defect-tolerant circuitry, and neuromorphic computing. Bipolar resistive switches based on metal oxides such as TiO2 have been identified as memristive devices primarily based on the “pinched hysteresis loop” that is observed in their current-voltage i-v characteristics. Here we ...
متن کاملMemristive switching of single-component metallic nanowires.
Memristors have recently generated significant interest due to their potential use in nanoscale logic and memory devices. Of the four passive circuit elements, the memristor (a two-terminal hysteretic switch) has so far proved hard to fabricate out of a single material. Here we employ electromigration to create a reversible passive electrical switch, a memristive device, from a single-component...
متن کاملB̄–B Mixing Constrains Topcolor–Assisted Technicolor
We argue that extended technicolor augmented with topcolor requires that all mixing between the third and the first two quark generations resides in the mixing matrix of left–handed down quarks. Then, the B̄d–Bd mixing that occurs in topcolor models constrains the coloron and Z ′ boson masses to be greater than about 5 TeV. This implies fine tuning of the topcolor couplings to better than 1%. bu...
متن کاملThermally assisted adiabatic quantum computation.
We study the effect of a thermal environment on adiabatic quantum computation using the Bloch-Redfield formalism. We show that in certain cases the environment can enhance the performance in two different ways: (i) by introducing a time scale for thermal mixing near the anticrossing that is smaller than the adiabatic time scale, and (ii) by relaxation after the anticrossing. The former can enha...
