Magnetic domain wall propagation under ferroelectric control

Nava Setter, Igor Stolichnov, Harry Joseph Trodahl, Evgeny Mikheev, Sebastian Riester

Control of magnetic domain walls (DWs) and their propagation is among the most promising development directions for future information-storage devices. The well-established tools for such manipulation are the spin-torque transfer from electrical currents a ...

Polarization Screening in Multiferroic (Ga,Mn)As/P(VDF-TrFE) Transistors

Nava Setter, Igor Stolichnov, Evgeny Mikheev, Sebastian Riester

Ferroelectric copolymers of polyvinylidene fluoride and trifluoroethylene are attractive gate materials because of a rather high remanent polarization, low dielectric permittivity, and easy integration on semiconductors due to the low processing temperatur ...

Toward a low-voltage multiferroic transistor: Magnetic (Ga,Mn)As under ferroelectric control

Nava Setter, Igor Stolichnov, Harry Joseph Trodahl, Sebastian Riester

The persistent field effect control of ferromagnetism in a diluted magnetic semiconductor by low-voltage polarizing pulses is demonstrated in a ferroelectric gate field effect transistor configuration. The Curie temperature of the (Ga,Mn)As channel is unam ...

Control of Ferromagnetism in a (Ga,Mn)As - Based Multiferroic System via a Ferroelectric Gate

Nava Setter, Igor Stolichnov, Harry Joseph Trodahl, Sebastian Riester

We report the implementation of a ferroelectric gate field effect transistor (FeFET) with a ferromagnetic (Ga,Mn)As conducting channel. The Curie temperature T-C in the channel is modulated by non-volatile poling of the gate. The ferroelectric state, and t ...
