Evidence of two dimensionality in quasi-one-dimensional cobalt oxides.
The quasi-one-dimensional (Q1D) cobalt oxides A(N + 2)Co(n + 1)O(3n + 3) (A = Ca, Sr, and Ba, n = 1 - infinity) were investigated by muon-spin spectroscopy under applied pressures of up to 1.1 GPa. The relationship between the onset Néel temperature T(on)(N) and the interchain distance (d(ic)), which increases monotonically with n, is well fitted by the formula T(N)/T(N,0) = (1 - d(ic)/d(ic,o)(...
متن کاملTheory of thermodynamic magnetic oscillations in quasi-one-dimensional conductors.
The second order correction to free energy due to the interaction between electrons is calculated for a quasi-one-dimensional conductor exposed to a magnetic field perpendicular to the chains. It is found that specific heat, magnetization and torque oscillate when the magnetic field is rotated in the plane perpendicular to the chains or when the magnitude of magnetic filed is changed. This new ...
متن کاملQuasi-one-dimensional particle-in-cell simulation of magnetic nozzles
A method for the quasi-one-dimensional simulation of magnetic nozzles was developed and simulations of a magnetic nozzle were performed. The effects of the density variation due to plasma expansion and the magnetic field forces on ion acceleration were investigated. The density variation only weakly affects ion acceleration. Magnetic field forces acting on the electrons were found to be respons...
متن کاملSuperconductivity of Quasi-One-Dimensional Electrons in Strong Magnetic Field
The superconductivity of quasi-one-dimensional electrons in the magnetic field is studied. The system is described as the one-dimensional electrons with no frustration due to the magnetic field. The interaction is assumed to be attractive between electrons in the nearest chains, which corresponds to the lines of nodes of the energy gap in the absence of the magnetic field. The effective interac...
متن کاملDisordered Bose-Einstein condensates in quasi-one-dimensional magnetic microtraps.
We analyze the effects of a random magnetic potential in a microfabricated waveguide for ultracold atoms. We find that the shape and position fluctuations of a current carrying wire induce a strong Gaussian correlated random potential with a length scale set by the atom-wire separation. The theory is used to explain quantitatively the observed fragmentation of the Bose-Einstein condensates in a...
