Commensurate and Incommensurate Structure of the Neutron Cross Section in LaSrCu and YBaCuO
نویسنده
چکیده
We study the evolution of the d-wave neutron cross-section with variable frequency ω and fixed T (below and above Tc) in two different cuprate families. The evolution from incommensurate to commensurate to incommensurate peaks is rather generic within an RPA-like scheme. This behavior seems to be in reasonable accord with experiments, and may help distinguish between this and the “stripe” scenario.

Field Dependence of Magnetic Ordering in Kagomé-Staircase Compound Ni3V2O8
We present powder and single-crystal neutron diffraction and bulk measurements of the Kagomé-staircase compound Ni3V2O8 (NVO) in fields up to 8.5T applied along the c direction. (The Kagomé plane is the a−c plane.) This system contains two types of Ni ions, which we call “spine” and “cross-tie.” Our neutron measurements can be described with the paramagnetic space group Cmca for T<15K and each ...
متن کاملFerroelectricity induced by acentric spin-density waves in YMn2O5.
The commensurate and incommensurate magnetic structures of the magnetoelectric system YMn2O5, as determined from neutron diffraction, were found to be spin-density waves lacking a global center of symmetry. We propose a model, based on a simple magnetoelastic coupling to the lattice, which enables us to predict the polarization based entirely on the observed magnetic structure. Our data accurat...
متن کاملExperimental comparison of thermal neutron absorption cross section in nano and micro particles
The neutron collision cross-section is important in neutron use for a specific job, such as neutron therapy or even in nuclear reactors. In calculating computational codes such as MCNP, only information from the neutron-to-mass collision information contained in the computational code library is used, in the case of nanoscale particles in contrast to the mass of materials and / or particulate m...
متن کاملCommensurate-incommensurate magnetic phase transition in magnetoelectric single crystal LiNiPO(4).
Neutron scattering studies of single crystal LiNiPO4 reveal a spontaneous first-order commensurate-incommensurate magnetic phase transition. Short- and long-range incommensurate phases are intermediate between the high temperature paramagnetic and the low temperature antiferromagnetic phases. The modulated structure has a predominant antiferromagnetic component, giving rise to satellite peaks i...
متن کاملField-induced incommensurate spin structure of TbNiAl4
TbNiAl4 exhibits incommensurate and commensurate magnetic ordering as a function of temperature. As a function of applied field it undergoes a series of magnetic phase transitions. The first of these transitions, into an intermediate spin arrangement, is the source of a large inverse magnetocaloric effect, an unusual result given that an aligning field is being applied. This has potential uses ...
