摘要：

Using a scanning tunneling microscope we imaged Abrikosov vortex lattices in 2H-NbSe2. At a reduced temperature of T/T(c) = 0.6 we found a distinct decrease of the vortex-core radius with increasing magnetic field. Even at low fields H/H(c)2 << 1, the effect of vortex-vortex interactions on the spatial variation of the order parameter DELTA(rho), is clearly evident. In order to interpret the experimental results the microscopic equations of the superconducting state are solved self-consistently. A good quantitative agreement is obtained without any variational free parameters.
