چکیده
Demagnetization in a thin film due to terahertz pulse of magnetic field is investigated. Linearized Landau-Lifshitz-Gilbert (LLG) equation the Fourier space describe magnetization dynamics derived, and spin wave time evolution studied. Finally, demagnetization recent experimental observations on similar system compared. As result, marginal role loss established.

Extremely Nonperturbative Nonlinearities in GaAs Driven by Atomically Strong Terahertz Fields in Gold Metamaterials.
Terahertz near fields of gold metamaterials resonant at a frequency of 0.88 THz allow us to enter an extreme limit of nonperturbative ultrafast terahertz electronics: Fields reaching a ponderomotive energy in the keV range are exploited to drive nondestructive, quasistatic interband tunneling and impact ionization in undoped bulk GaAs, injecting electron-hole plasmas with densities in excess of...

15 صفحه اولNonlinear spin control by terahertz-driven anisotropy fields
Future information technologies, such as ultrafast data recording, quantum computation or spintronics, call for ever faster spin control by light1–16. Intense terahertz pulses can couple to spins on the intrinsic energy scale of magnetic excitations5,11. Here, we explore a novel electric dipole-mediated mechanism of nonlinear terahertz-spin coupling that is much stronger than linear Zeeman coup...
متن کاملMultiscale modeling of current-driven magnetization dynamics
Understanding magnetization dynamics in magnetic materials under external current control plays a vital role in magnetic storage devices, such as magnetoresistance random access memories and race-track memories. In this presentation, we will discuss how to model such a phenomenon at different spatial and temporal scales. Consequently, a series of models is obtained with increasing accuracy. Eff...
متن کاملSpin-charge coupled dynamics driven by a time-dependent magnetization
The spin-charge coupled dynamics in a thin, magnetized metallic system are investigated. The effective driving force acting on the charge carriers is generated by a dynamical magnetic texture, which can be induced, e.g., by a magnetic material in contact with a normal-metal system. We consider a general inversion-asymmetric substrate/normal-metal/magnet structure, which, by specifying the preci...
