✦ Synopsis

Some features of the vortex lattice in ideal type-II superconductors are calculated from Ginzburg-Landau theory for the entire ranges of applied magnetic fields H c2 6 H 6 H c2 or induction 0 6 B 6 l 0 H c2 and Ginzburg-Landau parameters j P 2 À1=2 . Results for the triangular and square flux-line lattices are compared with the results of the circular cell approximation. The exact magnetic field Bðx; yÞ and magnetization MðH ; jÞ are compared with often used approximate expressions, some of which deviate considerably or have limited validity. Useful limiting and fitting expressions are presented.
