(5.67). We recall that mc(t;ḡ) in this formula corresponds to the precessional dynamics under magnetic field applied along the easy axis. This dynamics has been extensively discussed in Chapter 4 and we shall use the basic formulas derived in that chapter in the expressions relevant to ...
Two-dimensional growth of α-MnTe is achieved at substrate temperatures of 370–450 °C. MnTe thin-film characterization and sample transfer to ARPES Details on sample characterization can be found in ref. 47. For ARPES experiments, the samples were transferred after growth into a ultrahigh...
The second: the solar magnetic field (MFs) from synoptic magnetographs. The third: CI measured at the east limb. And the fourth (bottom) panel: CI at the west limb. The vertical thick dashed lines show the minimum times of the solar cycles. Full size image Cross-correlation analysis is ...
We investigate the ground state of a two-dimensional quantum particle in a magnetic field where the field vanishes nondegenerately along a closed curve. We show that the ground state concentrates on this curve ase/h tends to infinity, wheree is the charge, and that the ground state energy ...
1 Holographic correspondence posits an equivalence between Einstein's general relativity in the bulk of a 5 dimensional hypothet- ical space with a black hole at the center and strongly coupled finite temperature quantum field theory at finite on the 4D boundary [25– 27]. Concretely, it maps ...
A sensor suitable for determining the direction of a two-dimensional magnetic field is Known from EP 1182461. The sensor comprises a magnetic field concentrator with a flat shape and two magnetic field sensors that comprise at least one Hall element whereby the Hall elements are arranged in the...
The chapter discusses magnetocrystalline anisotropy (MCA), early work in this field, dipole–dipole interaction and related anisotropy, magnetoelastic anisotropy, perpendicular magnetic anisotropy, x-ray magnetic circular dichroism (XMCD), X-ray magnetic linear dichroism (XMLD) for anisotropy measurements...
It was demonstrated that under a constant electric field, magnetic fluids can form structured lattices or autowaves in thin layers [48,49]. These processes are associated with a local concentration of nanoparticles and can be associated with a change in color, but the mechanisms of such ...
