| We study the spin coupling of protons which are localized in dense neutron star matter. The effective spin interaction of neighbouring protons is induced by the direct spin interaction of protons with the background neutrons. The exchange integral of the effective proton-proton spin interaction is calculated. The interaction is ferromagnetic in a wide range of neutron star matter parameters. |
