Intermediate state switching dynamics in magnetic double layer nanopillars grown by molecular beam epitaxy
N. Müsgens, T. Maassen, E. Maynicke +6
We observe a stable intermediate resistance switching state in the current perpendicular to plane geometry for all Co/Cu/Co double layer nanopillar junctions grown by molecular bea…
Mapping of spin lifetimes to electronic states in n-type GaAs near the metal-insulator transition
L. Schreiber, M. Heidkamp, T. Rohleder +2
The longest spin lifetimes in bulk n-GaAs exceed 100 ns for doping concentrations near the metal-insulator transition (J.M. Kikkawa, D.D. Awschalom, Phys. Rev. Lett. 80, 4313 (1998…
Complex ferromagnetic state and magnetocaloric effect in single crystalline Nd_{0.7}Sr_{0.3}MnO_{3}
R. Venkatesh, M. Pattabiraman, S. Angappane +6
The magnetocaloric effect in single crystalline Nd_{0.7}Sr_{0.3}MnO_{3} is investigated by measuring the field-induced adiabatic change in temperature which reveals a single negati…
Anisotropic Electron Spin Lifetime in (In,Ga)As/GaAs (110) Quantum Wells
L. Schreiber, D. Duda, B. Beschoten +3
Anisotropic electron spin lifetimes in strained undoped (In,Ga)As/GaAs (110) quantum wells of different width and height are investigated by time-resolved Faraday rotation and time…
Low-frequency noise and tunnelling magnetoresistance in Fe(110)/MgO(111)/Fe(110) epitaxial magnetic tunnel junctions
R. Guerrero, F. G. Aliev, R. Villar +6
We report on tunnelling magnetoresistance (TMR), current-voltage (IV) characteristics and low frequency noise in epitaxially grown Fe(110)/MgO(111)/Fe(110) magnetic tunnel junction…
Charge density waves in Sr_14-xCa_xCu_24O_41: electron correlations vs. structural effects
K. -Y. Choi, M. Grove, P. Lemmens +7
We report inelastic light scattering experiments in the spin-chain and ladder system Sr_14-xCa_xCu_24O_41. A depletion of an electronic background is observed for 0 < x < 5 at low…
