Explicit dependencies of the local density of states and the magnetizationlocal density of states have been obtained around magnetic point defects in atwo-dimensional electron gas with Rashba spin-orbit interaction . Theexpressions are given in the Born approximation for arbitrary magnitude andorientation of the defect magnetic moment, and for arbitrary size of theconstant of spin-orbit interaction alpha/. On the basis of our asymptoticallyexact formulas a procedure for the determination of the constant alpha/ in STMexperiments is proposed. The novel analytical results are compared with thenumerical and approximate results of previous work. At variance with earlierwork we find that that magnetic scattering in the presence of spin-orbitinteraction does not modify the local density of states and that the spintexture resulting from in-plain orientation of the defect magnetic moment, andelastic scattering, is not a purely in-plane spin texture.
