 abstract

Magnetic structure of a perfect triangular
lattice at relatively low fields is numerically calculated
by superposing isolated flux lines based on the
GinzburgLandau theory. It is found that the magnetic flux
density is fairly uniform spatially and the difference
between the maximum and minimum values is
25~\% when the fluxoid spacing, $a_{\rm f}$, is equal
to the penetration depth, $\lambda$, and the GL parameter
$\kappa=50$. The obtained magnetic structure is expressed
in the Fourier series and the expansion summed terms are
obtained as a function of $\kappa$ and $a_{\rm
f}/\lambda$. It is seen that the number of coefficients
needed for reconstruction becomes small with increasing
magnetic flux density.
