Discovery of a binary icosahedral quasicrystal in ScZn
P. C. Canfield, M. L. Caudle, C. -S. Ho +8
We report the discovery of a new binary icosahedral phase in a Sc-Zn alloy obtained through solution-growth, producing millimeter-sized, facetted, single grain, quasicrystals that…
Direct imaging of the structural domains in iron pnictides AFe2As2 (A = Ca, Sr, Ba)
M. A. Tanatar, A. Kreyssig, S. Nandi +5
The parent compounds of recently discovered iron-arsenide superconductors, FeAs with alkaline earth =Ca, Sr, Ba, undergo simultaneous structural and magnetic phase tr…
Competition and coexistence of antiferromagnetism and superconductivity in underdoped Ba(Fe0.953Co0.047)2As2
D. K. Pratt, W. Tian, A. Kreyssig +7
Neutron and x-ray diffraction studies show that the simultaneous first-order transition to an orthorhombic and antiferromagnetic (AFM) ordered state in BaFe2As2 splits into two tra…
Structural, magnetic and superconducting phase transitions in CaFe2As2 under ambient and applied pressure
P. C. Canfield, S. L. Bud'ko, N. Ni +7
At ambient pressure CaFe2As2 has been found to undergo a first order phase transition from a high temperature, tetragonal phase to a low temperature orthorhombic / antiferromagneti…
Probing fractal magnetic domains on multiple length scales in Nd2Fe14B
A. Kreyssig, R. Prozorov, C. D. Dewhurst +3
Using small-angle neutron scattering, we demonstrate that the complex magnetic domain patterns at the surface of Nd2Fe14B, revealed by quantitative Kerr and Faraday microscopy, pro…
Itinerant magnetic excitations in antiferromagnetic CaFe2As2
S. O. Diallo, V. P. Antropov, T. G. Perring +8
Neutron scattering measurements of the magnetic excitations in single crystals of antiferromagnetic CaFe2As2 reveal steeply dispersive and well-defined spin waves up to an energy o…
