The unusual magnetic properties of a novel low-dimensional quantumferrimagnet Cu$_2$Fe$_2$Ge$_4$O$_{13}$ are studied using bulk methods, neutrondiffraction and inelastic neutron scattering. It is shown that this materialcan be described in terms of two low-dimensional quantum spin subsystems, onegapped and the other gapless, characterized by two distinct energy scales.Long-range magnetic ordering observed at low temperatures is a cooperativephenomenon caused by weak coupling of these two spin networks.Comment: 4 pages, 4 figure
