Engineering and improving the magnetic properties of thin Fe layers through exchange coupling with hard magnetic Dysprosium layers
M. Ehlert, H. S. Körner, T. Hupfauer +3
We report on a comprehensive study of the magnetic coupling between soft magnetic Fe layers and hard magnetic Dysprosium (Dy) layers at low temperatures (4.2 - 120K). For our exper…
Giant enhancement of spin detection sensitivity in (Ga,Mn)As/GaAs Esaki diodes
Junichi Shiogai, Mariusz Ciorga, Martin Utz +6
We investigate the correlation between spin signals measured in three-terminal (3T) geometry by the Hanle effect and the spin accumulation generated in a semiconductor channel in a…
Raman spectroscopy of the interlayer shear mode in few-layer MoS2 flakes
G. Plechinger, S. Heydrich, J. Eroms +3
Single- and few-layer MoS2 has recently gained attention as an interesting new material system for opto-electronics. Here, we report on scanning Raman measurements on few-layer MoS…
Nonuniform current density and spin accumulation in a 1 μm thick n-GaAs channel
Bernhard Endres, Mariusz Ciorga, Robert Wagner +6
The spin accumulation in an n-GaAs channel produced by spin extraction into a (Ga,Mn)As contact is measured by cross-sectional imaging of the spin polarization in GaAs. The spin po…
Hysteretic magnetoresistance and thermal bistability in a magnetic two-dimensional hole system
Ursula Wurstbauer, Cezary Śliwa, Dieter Weiss +2
Colossal negative magnetoresistance and the associated field-induced insulator-to-metal transition, the most characteristic features of magnetic semiconductors, are observed in n-t…
Local spin valve effect in lateral (Ga,Mn)As/GaAs spin Esaki diode devices
Mariusz Ciorga, Christian Wolf, Andreas Einwanger +3
We report on a local spin valve effect observed unambiguously in lateral all-semiconductor all-electrical spin injection devices, employing p+-(Ga,Mn)As/n+-GaAs Esaki diode structu…
