We present spin-polarized scanning tunneling microscopy Measurements demonstrating spin-polarizations of tip to 80 % for Co islands on a Pt(111) surface and a tunnel magneto resistance of 850 similar to% between the islands and an anti-ferromagnetic Cr-co ...
Conditions for a transition from the insulator (I) to metal (M) state in the electron system of highly oriented pyrolytic graphite (HOPG) have been studied by means of magnetotransport measurements in a broad temperature range (0.3–150 K). In magnetic fiel ...
We present experiments on the magnetic-field-dependent thermal transport in the spin-1/2 ladder system (C5H12N)(2)CuBr4. The thermal conductivity kappa(B) is only weakly affected by the field-induced transitions between the gapless Luttinger-liquid state r ...
We describe a setup for the x-ray detection of ferromagnetic resonance in the longitudinal geometry using element-specific transmission measurements. Thin magnetic film samples are placed in a static magnetic field collinear with the propagation direction ...
This paper applies nonequilibrium thermodynamics in the linear regime to describe spin diffusion and magnetoresistance effects and to examine the effect of spin mixing on transport through collinear magnetic layers. To demonstrate the method, it treats ana ...

We show that the ferromagnetic anisotropy of a thin crystalline Fe3O4 film can be manipulated in situ via the application of tunable stress. The stress is exerted by a piezoelectric actuator, onto which the Fe3O4 film is cemented. The strain in the sample ...
We observed the second harmonic voltage response of pseudo-spin valves subjected to currents oscillating at frequencies in the sub-kilohertz range. Peaks appear in its magnetic field dependence, with a signal-to-noise ratio equal to or greater than the mag ...
The efficiency of magnetization transfer between different spins S such as chemically inequivalent carbon-13 nuclei in solid samples that are spinning at high frequencies about the magic angle can be enhanced by a phase-alternated recoupling irradiation sc ...
Developments towards an understanding of the nature of conductance at the interface between two different metallic layers – ferromagnetic and non magnetic – as well as the discovery of giant magnetoresistance have stirred attention from both the scientific ...
This thesis reports on the optical properties of fullerene molecules forming nanoscale crystals grown on ultrathin NaCl films on Au(111) investigated by Scanning Tunneling Microscope (STM)-induced light emission spectroscopy. In this regard, an existing op ...
