2014 We have investigated magnetic domain structures in (111) Silicon-Iron single crystals by means of Lang’s method, Kerr effect and Bitter patterns. Two clear configurations have been observed. The first one (structure A) is made of domains along the 011 > directions of the (111) plane, the second one (structure B) of domains along the 211 > directions. Models are presented for both...

Several studies (e.g. Kerr, 1987; 1993; Diwadkar, Carpenter & Just, 2000) have asked participants to report the final location of a point after imaginary moves through 2D and 3D arrays. The results suggest that visualizing 3D space is inherently more difficult than 2D visualization, and may even use different brain mechanisms. However, 2D and 3D trials were presented in separate blocks, so part...

The Cauchy problem for the scalar wave equation in the Kerr geometry is considered, with initial data which is smooth and compactly supported outside the event horizon. A time-independent energy estimate for the outgoing wave is obtained. As an application we estimate the outgoing energy for wave-packet initial data, uniformly as the support of the initial data is shifted to infinity. The main ...

Co2FeSi(100) films with L21 structure deposited onto MgO(100) were studied exploiting both longitudinal (LMOKE) and quadratic (QMOKE) magneto-optical Kerr effect. The films exhibit a huge QMOKE signal with a maximum contribution of up to 30mdeg, which is the largest QMOKE signal in reflection that has been measured thus far. This large value is a fingerprint of an exceptionally large spin-orbit...

We are familiar with Dirac equation in flat space by which we can investigate the behaviour of half-integral spin particle. With the introduction of general relativistic effects the form of the Dirac equation will be modified. For the cases of different background geometry like Kerr, Schwarzschild etc. the corresponding form of the Dirac equation as well as the solution will be different. In 19...

The radiation gauges used by Chrzanowski (his IRG/ORG) for metric reconstruction in the Kerr spacetime seem to be over-specified. Their specification consists of five conditions: four, which we treat here as valid gauge conditions, plus an additional condition on the trace of the metric perturbation. In this work, we utilize a newly developed form of the perturbed Einstein equations to establis...

We show the existence of the full compound asymptotics of solutions to the scalar wave equation on long-range non-trapping Lorentzian manifolds modeled on the radial compactification of Minkowski space. In particular, we show that there is a joint asymptotic expansion at null and timelike infinity for forward solutions of the inhomogeneous equation. In two appendices we show how these results a...

We study theoretically the origin and mechanism of the ultrafast inverse Faraday effect, which is a magnetooptical effect, attracting much interest nowadays. Laser-induced subpicosecond spin dynamics in hydrogenlike systems and isolated many-electron atoms are investigated in order to get insight into this process. We show that the stimulated Raman scattering process leads to a change of the ma...
