“…Recently introduced ultrafast magneto-optical techniques [3] permit one to directly observe the time dependent magnetization process down to picosecond resolution [4]. Early damping of domain wall relaxation with increasing frequency is observed in thin metallic plates if rotations can simultaneously occur [5].…”

We present a few significant advances in methods and concepts of magnetic measurements, aimed both at providing novel routes in the characterization of hard and soft magnetic materials and at improving our basic knowledge of the magnetization process. We discuss, in particular, investigation methods and experimental arrangements that have been developed in recent times for: 1) Hysteresis loop determination in extra-hard magnets by means of Pulsed Field Magnetometry; 2) Broadband observation of domain wall dynamics by highspeed stroboscopical Kerr techniques; 3) Entropy measurements in magnetocaloric materials by calorimetry in magnetic field. While pertaining to somewhat independent fields of investigation, all these measuring techniques have in common a solid approach to the underlying physical phenomenology and have a potential for further developments.

The terahertz radiation-induced conductivity and dielectric polarization tensors as well as the Faraday and Kerr rotation angles and the non-equilibrium spin textures are studied for twodimensional electron gas with strong spin-orbit coupling subjected to high magnetic field and to tunable periodic potential of a two-dimensional gated superlattice. It is found that both real and imaginary parts of the frequency-dependent induced conductivity approach maximum values with sharp and detectable peaks at frequencies corresponding to the inter-subband transitions between spin-split magnetic subbands. The observed properties of the conductivity tensor frequency dependence are applied for the description of the Kerr and Faraday rotation angles which can be used as another experimental tool for describing the electron gas in periodic structures with significant spin-orbit coupling. The formation of radiation-induced spin textures is predicted having both inplane and out-of-plane components with space distribution scale comparable to the superlattice cell size which can be observed experimentally.

“…It is evident that the lattice asymmetry with respect to the x ↔ y interchange transform has lead to a slight but distinct asymmetry in the current amplitude of around 12%, and the dominating S y (E x ) and S x (E y ) induced spin components demonstrate the well-known transverse in-plane character of the induced spin for linear Rashba SO coupling. It should be noted that the local probe measurements of induced spin polarizations (or magnetization) may detect the non-zero static and dynamic local magnetization 40 in the spot under the probe even in case of total zero mean spin value (8) and (b) spin polarization (9) induced by the dc electric field applied along x (solid curves) and y (dashed curves). A conventional linear dependence of the charge current on the applied electric field throughout the whole range of fields and almost linear dependence for the significant non-zero induced spin components Sy(Ex) and Sx(Ey) are visible.…”

An expansion of the nearly free-electron model constructed by Frantzeskakis, Pons and Grioni [Phys. Rev. B 82, 085440 (2010)] describing quantum states at Bi/Si(111) interface with giant spinorbit coupling is developed and applied for the band structure and spin polarization calculation, as well as for the linear response analysis for charge current and induced spin caused by dc field and by electromagnetic radiation. It is found that the large spin-orbit coupling in this system may allow resolving the spin-dependent properties even at room temperature and at realistic collision rate. The geometry of the atomic lattice combined with spin-orbit coupling leads to an anisotropic response both for current and spin components related to the orientation of the external field. The in-plane dc electric field produces only the in-plane components of spin in the sample while both the in-plane and out-of-plane spin components can be excited by normally propagating electromagnetic wave with different polarizations.
