We consider the effect of electron-electron interactions on the
current-in-plane (CIP) conductivity and exchange coupling energy of a disordered metallic magnetic multilayer. We analyze its dependence
on the value of ferromagnetic splitting of conducting electrons and on
ferromagnetic-layers relative magnetizations orientation. We show that the contribution to the CIP conductivity and exchange coupling
energy as a periodic function of the angle of magnetizations relative orientation experience 
transition
depending on the characteristic energies, i.e. ferromagnetic splitting of
the conducting electrons and the Thouless energy of paramagnetic layer.
