The pressure dependence of the vortex core in rotating /sup 3/He-B is studied in the Ginzburg-Landau formalism with two distinct models of the strong-coupling corrections. The parametrization of Sauls and Serene (Phys. Rev. B 24, 183 (1981)) predicts a transition from a core with large magnetic moment below approx.10 bars to one with small magnetic moment for higher pressures, in qualitative agreement with experiments. The earlier one-parameter model of Brinkman, Serene, and Anderson predicts no such transition, with the core having a large moment for all values of the parameter delta.
