Local charge and spin currents in magnetothermal landscapes
Mathias Weiler, Matthias Althammer, Franz D. Czeschka +8
A scannable laser beam is used to generate local thermal gradients in metallic (Co2FeAl) or insulating (Y3Fe5O12) ferromagnetic thin films. We study the resulting local charge and…
Spin pumping with coherent elastic waves
M. Weiler, H. Huebl, F. S. Goerg +3
We show that the resonant coupling of phonons and magnons can be exploited to generate spin currents at room temperature. Surface acoustic wave (SAW) pulses with a frequency of 1.5…
Magneto-optical imaging of voltage-controlled magnetization reorientation
A. Brandlmaier, M. Brasse, S. Geprägs +3
We study the validity and limitations of a macrospin model to describe the voltage-controlled manipulation of ferromagnetic magnetization in nickel thin film/piezoelectric actuator…
Fermi Surface of the Electron-doped Cuprate Superconductor Nd_{2-x}Ce_xCuO_{4} Probed by High-Field Magnetotransport
M. V. Kartsovnik, T. Helm, C. Putzke +10
We report on the study of the Fermi surface of the electron-doped cuprate superconductor NdCeCuO by measuring the interlayer magnetoresistance as a function of th…
