Title: Magnetic exchange disorder in low-dimensional quantum magnets

Abstract

Low-dimensional quantum magnetism is currently of great interest due to the fact that reduced dimensionality can support strong quantum fluctuations, which may lead to unusual phenomena and quantum-critical behavior. The effect of random exchange strengths in two-dimensional (2D) antiferromagnets is still not fully understood despite much effort. This project aims to rectify this by investigating the high-field properties of the 2D coordination polymer (QuinH) 2Cu(Cl xBr 1-x) 4.2H 2O. The exchange pathway is through Cu-Halide-Cu bonds, and by randomizing the proportion of chlorine and bromine atoms in the unit cell, disorder can be introduced into the system.

  • This report is a compilation of the data obtained from the MTF measurements made of the superconducting low-[beta] quadrupole magnets and spools used in the low-[beta] inserts at B0 and D0 in the Tevatron. The measurements were done at 4.6K. Very high gradients are required in these quadrupoles to achieve a value of the amplitude function [beta], of 0.25m at the interaction point. The transfer function, viz. the gradient for a given current in the coils has a nominal value of 0.2913 T/cm/kA in the two shell quadrupoles and 0.5825 T/cm/kA in the one shell quadrupole built from segmented 5-in-1more » conductor. As a comparison the transfer constants in the superconducting lattice quads in the Tevatron have a transfer constant of [approx]0.173T/cm/kA. This improvement in performance is the result of the R D effort, at Fermilab, that preceeded the construction of these magnets. In those cases where the data are not presented in the same way as they are reported by MTF, the author explains the method by which the data have been reduced to produce the numbers in this report. Not all the available data are reproduced in this report. They are stored in one or more data bases and can be retrieved when needed.« less
