Thermo-Electric Properties of Quantum Point Contacts
H. van Houten, L. W. Molenkamp, C. W. J. Beenakker +1
I. Introduction II. Theoretical background (Landauer-Buttiker formalism of thermo-electricity, Quantum point contacts as ideal electron waveguides, Saddle-shaped potential) III. Ex…
Tunneling magnetoresistance in devices based on epitaxial NiMnSb with uniaxial anisotropy
J. Liu, E. Girgis, P. Bach +4
We demonstrate tunnel magnetoresistance (TMR) junctions based on a tri layer system consisting of an epitaxial NiMnSb, aluminum oxide and CoFe tri layer. The junctions show a tunne…
Direct observation of the Aharonov-Casher phase
M. Koenig, A. Tschetschetkin, E. M. Hankiewicz +7
Ring structures fabricated from HgTe/HgCdTe quantum wells have been used to study Aharonov-Bohm type conductance oscillations as a function of Rashba spin-orbit splitting strength.…
Quantitative detection of electrically injected spin accumulation in GaAs using the magneto-optical Kerr effect
A. V. Kimel, A. Kirilyuk, P. Grabs +5
Using an ultra sensitive magneto-optical Kerr rotation setup we have observed electrical spin injection from (Zn,Mn)Se into bulk GaAs and quantified the spin injection efficiency.…
Spin-lattice relaxation of Mn-ions in ZnMnSe/ZnBeSe quantum wells measured under pulsed photoexcitation
M. K. Kneip, D. R. Yakovlev, M. Bayer +6
The dynamics of spin-lattice relaxation of the Mn-ions in (Zn,Mn)Se-based diluted-magnetic-semiconductor quantum wells is studied by time-resolved photoluminescence. The spin-latti…
Self Assembled II-VI Magnetic Quantum Dot as a Voltage-Controlled Spin-Filter
C. Gould, A. Slobodskyy, T. Slobodskyy +6
A key element in the emergence of a full spintronics technology is the development of voltage controlled spin filters to selectively inject carriers of desired spin into semiconduc…
