Microstructure of precipitates and magnetic domain structure in an annealed Co38Ni33Al29 shape memory alloy
B. Bartova, N. Wiese, D. Schryvers +2
The microstructure of a CoNiAl FSMA was determined by conventional transmission electron microscopy, electron diffraction studies together with advanced microscopy techniques and i…
Direct observation of domain wall structures in curved permalloy wires containing an anti-notch
C. W. Sandweg, N. Wiese, D. McGrouther +6
The formation and field response of head-to-head domain walls in curved permalloy wires, fabricated to contain a single anti-notch, have been investigated using Lorentz microscopy.…
On the scaling behaviour of cross-tie domain wall structures in patterned NiFe elements
N. Wiese, S. McVitie, J. N. Chapman +2
The cross-tie domain wall structure in micrometre and sub-micrometre wide patterned elements of NiFe, and a thickness range of 30 to 70nm, has been studied by Lorentz microscopy. W…
Strong temperature dependence of antiferromagnetic coupling in CoFeB/Ru/CoFeB
N. Wiese, T. Dimopoulos, M. Rührig +4
The temperature dependence of saturation and spin-flop fields for artificial ferrimagnets (AFi) based on antiparallel coupled CoFeB/Ru/CoFeB trilayers has been investigated in a te…
Switching of sub-micrometer sized, antiferromagnetically coupled CoFeB/Ru/CoFeB trilayers
N. Wiese, T. Dimopoulos, M. Ruhrig +2
This work reports on the magnetic reversal of sub-micrometer sized elements consisting of an CoFeB/Ru/CoFeB artificial ferrimagnet (AFi). The elements were patterned into ellipses…
Antiferromagnetically coupled CoFeB/Ru/CoFeB trilayers
N. Wiese, T. Dimopoulos, M. Ruhrig +3
This work reports on the magnetic interlayer coupling between two amorphous CoFeB layers, separated by a thin Ru spacer. We observe an antiferromagnetic coupling which oscillates a…
