Abstract

First we calculate the texture of a Mermin-Ho vortex in a field of 284 Oe and compare its energy with the energies of singular vortices in3He-A as a function of rotation speed and temperature. Then we calculate the order parameter components ψ r , ψφ and ψ z (r, ф,z are cylindrical coordinates) for an isolated vortex line in3He-B. We find that in the core region the transverse components ψ r and ψφ are strongly reduced in comparison to the component ψ z along the rotation axis. A strong magnetic field has the reverse effect: ψ z is reduced in comparison to ψ r and ψφ. Finally we calculate the corrections of order (1−T/T c ) to the Ginzburg-Landau solutions. These yield an interesting structure of the vortex core. For radial distances large compared to the coherence length, ψφ is reduced as the temperature decreases.
