Extremely low energy ARPES of quantum well states in cubic-GaN/AlN and GaAs/GaAlAs heterostructures
Mahdi Hajlaoui, Stefano Ponzoni, Michael Deppe +6
Quantum well (QW) heterostructures have been extensively used for the realization of a wide range of optical and electronic devices. Exploiting their potential for further improvem…
Quasi 2D electronic states with high spin-polarization in centrosymmetric MoS bulk crystals
Mathias Gehlmann, Gustav Bihlmayer, Irene Aguilera +9
Time reversal dictates that nonmagnetic, centrosymmetric crystals cannot be spin-polarized as a whole. However, it has been recently shown that the electronic structure in these cr…
Enhanced ferrimagnetism in auxetic NiFe2O4 in the crossover to the ultrathin film limit
Michael Hoppe, Sven Döring, Mihaela Gorgoi +2
We investigate the sensitive interplay between magnetic, electronic and structural properties in the ferrimagnetic oxide NiFe2O4. Emphasis is placed on the impact of reduced dimens…
Spatially resolved observation of uniform precession modes in spin-valve systems
Alexander M. Kaiser, Carsten Wiemann, Stefan Cramm +1
Using time-resolved photoemission electron microscopy the excitation of uniform precession modes in individual domains of a weakly coupled spin-valve system has been studied. A cou…
Structural and magneto-transport characterization of Co_2Cr_xFe_(1-x)Al Heusler alloy films
A. D. Rata, H. Braak, D. E. Buergler +2
We investigate the structure and magneto-transport properties of thin films of the Co_2Cr_xFe_(1-x)Al full-Heusler compound, which is predicted to be a half-metal by first-principl…
