Experimental observation of lattice distortions due to a flux line lattice in niobium
journal contribution
posted on 2006-05-11, 13:24 authored by Klaus-Ulrich Neumann, Feodor Kusmartsev, H-J. Lauter, O. Scharpf, T.J. Smith, K.R.A. ZiebeckA polarized neutron scattering investigation of the flux line lattice in the type-II superconductor
niobium is reported. A modulation of the nuclear lattice has been detected, and the magnitude of the
rst Fourier component of the lattice distortion established relative to the magnitude of the magnetic
scattering. This constitutes the rst experimental observation of lattice distortions due to the presence
of magnetic flux lines within the bulk of a type-II superconductor. Using a simple microscopic model the
lattice distortion in niobium is estimated. A new mechanism is suggested for the coupling of the flux line
lattice to the crystallographic lattice. The experimental technique opens up the possibility of investigating
the microscopic mechanism of flux line - nuclear lattice interactions, in particular the pinning of flux lines
within the bulk of a type-II superconductor.
