Fingerprinting the magnetic behavior of antiferromagnetic nanostructures using remanent magnetization curves
M. J. Benitez, O. Petracic, H. Tüysüz +2
Antiferromagnetic (AF) nanostructures from Co3O4, CoO and Cr2O3 were prepared by the nanocasting method and were characterized magnetometrically. The field and temperature dependen…
Charge ordering of magnetic monopoles in triangular spin ice patterns
A. Schumann, B. Sothmann, P. Szary +1
Artificial spin ice offers the possibility to investigate a variety of dipolar orderings, spin frustrations and ground states. However, the most fascinating aspect is the realizati…
Spin Torques in Point Contacts to Exchange-Biased Ferromagnetic Films
I. K. Yanson, Yu. G. Naidyuk, O. P. Balkashin +6
Hysteretic magneto-resistance of point contacts formed between non-magnetic tips and single ferromagnetic films exchange-pinned by antiferromagnetic films is investigated. The anal…
Domain wall propagation in Permalloy nanowires with a thickness gradient
O. Petracic, P. Szary, H. Zabel +2
The domain wall nucleation and motion processes in Permalloy nanowires with a thickness gradient along the nanowire axis have been studied. Nanowires with widths, w = 250 nm to 3 u…
Origin of the reduced exchange bias in epitaxial FeNi(111)/CoO(111) bilayer
F. Radu, S. K. Mishra, I. Zizak +12
We have employed Soft and Hard X-ray Resonant Magnetic Scattering and Polarised Neutron Diffraction to study the magnetic interface and the bulk antiferromagnetic domain state of t…
Magnetic domain fluctuations in an antiferromagnetic film observed with coherent resonant soft x-ray scattering
S. Konings, C. Schuessler-Langeheine, H. Ott +4
We report the direct observation of slow fluctuations of helical antiferromagnetic domains in an ultra-thin holmium film using coherent resonant magnetic x-ray scattering. We obser…
