Modal frustration and periodicity breaking in artificial spin ice
R. Puttock, A. Manzin, V. Neu +4
Here an artificial spin ice (ASI) lattice is introduced that exhibits unique Ising and non-Ising behavior under specific field switching protocols because of the inclusion of coupl…
Quantitative assessment of pinning forces and the superconducting gap in NbN thin films from complementary magnetic force microscopy and transport measurements
T. Shapoval, H. Stopfel, S. Haindl +5
Epitaxial niobium-nitride thin films with a critical temperature of Tc=16K and a thickness of 100nm were fabricated on MgO(100) substrates by pulsed laser deposition. Low-temperatu…
Direct observation of superconducting vortex clusters pinned by a periodic array of magnetic dots in ferromagnetic/superconducting hybrid structures
T. Shapoval, V. Metlushko, M. Wolf +3
Strong pinning of superconducting flux quanta by a square array of 1 m-sized ferromagnetic dots in a magnetic-vortex state was visualized by low-temperature magnetic force micr…
Electronic phase separation in the slightly underdoped iron pnictide superconductor Ba(1-x)K(x)Fe(2)As(2)
J. T. Park, D. S. Inosov, Ch. Niedermayer +14
Here we present a combined study of the slightly underdoped novel pnictide superconductor Ba(1-x)K(x)Fe(2)As(2) by means of X-ray powder diffraction, neutron scattering, muon spin…
Symmetry and disorder of the vitreous vortex lattice in an overdoped BaFe_{2-x}Co_xAs_2 superconductor: Indication for strong single-vortex pinning
D. S. Inosov, T. Shapoval, V. Neu +14
The disordered flux line lattice in single crystals of the slightly overdoped aFe_{2-x}Co_xAs_2 (x = 0.19, Tc = 23 K) superconductor is studied by magnetization measurements, small…
2024 Roadmap on Magnetic Microscopy Techniques and Their Applications in Materials Science
D. V. Christensen, U. Staub, T. R. Devidas +50
Considering the growing interest in magnetic materials for unconventional computing, data storage, and sensor applications, there is active research not only on material synthesis…
