Electrical control of ferromagnetic state

چکیده
We report experiments where magnetization in GaMnAs ferromagnetic semiconductor is manipulated via strain or electric current. In both cases, charge carrier holes become partially polarized due to the anisotropic modification of holes spectra caused by spin–orbit interactions, and this polarization exerts spin torque sufficient to rotate ferromagnetic domains. & 2012 Elsevier B.V.

Electrical control of the ferromagnetic phase transition in cobalt at room temperature.
Electrical control of magnetic properties is crucial for device applications in the field of spintronics. Although the magnetic coercivity or anisotropy has been successfully controlled electrically in metals as well as in semiconductors, the electrical control of Curie temperature has been realized only in semiconductors at low temperature. Here, we demonstrate the room-temperature electrical ...
متن کاملOptimal Finite-time Control of Positive Linear Discrete-time Systems
This paper considers solving optimization problem for linear discrete time systems such that closed-loop discrete-time system is positive (i.e., all of its state variables have non-negative values) and also finite-time stable. For this purpose, by considering a quadratic cost function, an optimal controller is designed such that in addition to minimizing the cost function, the positivity proper...
متن کاملRe-entrant spin glass and Magnetoresistance in Co0.2Zn0.8Fe1.6Ti0.4O4 spinel oxide
We have investigated the static and dynamical response of magnetic clusters in Co0.2Zn0.8Fe1.6Ti0.4O4 spinel oxide, where a sequence of magnetic phase transitions, i.e, paramagnetic(PM) to ferromagnetic (FM) state at TC ≤ 270K and ferromagnetic to canted spin glass (CSG) state at Tf ≤ 125K is observed. The time dependence of remanent magnetization shows a non-equilibrium spin dynamics in the CS...

متن کاملRobust Adaptive Actuator Failure Compensation of MIMO Systems with Unknown State Delays
In this paper, a robust adaptive actuator failure compensation control scheme is proposed for a class of multi input multi output linear systems with unknown time-varying state delay and in the presence of unknown actuator failures and external disturbance. The adaptive controller structure is designed based on the SPR-Lyapunov approach to achieve the control objective under the specific assump...
