  We consider a two-component Bose-condensed mixture characterized by positive
s-wave scattering lengths. We assume equal densities and intra-species
interactions. By doing the Bogoliubov transformation of an effective
Hamiltonian we obtain the lower energy magnon dispersion incorporating the
superfluid entrainment between the components. We argue that p-wave pairing of
distinct bosons should be accompanied by self-localization of magnons and
formation of a magnetoroton. We demonstrate the effect on a model system of
particles interacting via step potentials.
