Practical use of waveguides for polarized neutrons studies
S. V. Kozhevnikov, T. Keller, Yu. N. Khaydukov +6
We present the use of planar waveguides to produce neutron microbeams in order to investigate magnetic micro-structures with a micrometric spatial resolution. We report experimenta…
Magnetic nanowires as permanent magnet materials
T. Maurer, F. Ott, G. Chaboussant +3
We present the fabrication of metallic magnetic nanowires using a low temperature chemical process. We show that pressed powders and magnetically oriented samples exhibit a very hi…
Giant Anisotropic Magneto-Resistance in ferromagnetic atomic contacts
M. Viret, M. Gabureac, F. Ott +3
Magneto-resistance is a physical effect of great fundamental and industrial interest since it is the basis for the magnetic field sensors used in computer read-heads and Magnetic R…
Dislocation-mediated plasticity in the AlCu θ-phase
D. Andre, Z. Xie, F. Ott +5
The deformation behaviour of the intermetallic AlCu-phase was investigated using atomistic simulations and micropillar compression, where slip on the unexpected {211} and {02…
Mechanisms of exchange bias with multiferroic BiFeO3 epitaxial thin films
H. Bea, M. Bibes, F. Ott +7
We have combined neutron scattering and piezoresponse force microscopy to study the relation between the exchange bias observed in CoFeB/BiFeO3 heterostructures and the multiferroi…
Biaxial Strain in the Hexagonal Plane of MnAs Thin Films: The Key to Stabilize Ferromagnetism to Higher Temperature
V. Garcia, Y. Sidis, M. Marangolo +7
The alpha-beta magneto-structural phase transition in MnAs/GaAs(111) epilayers is investigated by elastic neutron scattering. The in-plane parameter of MnAs remains almost constant…
