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…
Orphan spins and bound in-gap states in the antiferromagnet CaFeO
C. Stock, E. E. Rodriguez, N. Lee +11
CaFeO is an anisotropic antiferromagnet with two competing () and ($\uparrow \downarrow \uparrow \downar…
Field-induced criticality in a gapped quantum magnet with bond disorder
D. Hüvonen, S. Zhao, M. Månsson +6
Neutron diffraction and calorimetric measurements are used to study the field-induced quantum phase transition in piperazinium-Cu(ClBr) (, x=3.5% and x=7.5…
Field-induced inter-planar correlations in the high-temperature superconductor La1.88Sr0.12CuO4
A. T. Roemer, P. Jensen, H. Jacobsen +14
We present neutron scattering studies of the inter-planar correlations in the high-temperature superconductor La1.88Sr0.12CuO4 (T_c=27 K). The correlations are studied both in a ma…
Origin of Electric Field Induced Magnetization in Multiferroic HoMnO3
B. G. Ueland, J. W. Lynn, M. Laver +2
We have performed polarized and unpolarized small angle neutron scattering experiments on single crystals of HoMnO3 and have found that an increase in magnetic scattering at low mo…
Field Dependence of the Superconducting Basal Plane Anisotropy of TmNi2B2C
P. Das, J. M. Densmore, C. Rastovski +7
The superconductor TmNi2B2C possesses a significant four-fold basal plane anisotropy, leading to a square Vortex Lattice (VL) at intermediate fields. However, unlike other members…
