We {characterize the multipartite entanglement in a quantum system by thequantity} which vanishes if only the quantum system may be decomposed into twoweakly entangled subsystems, unlike measures of multipartite entanglementintroduced before. We refer to this {quantity} as the minimal entanglement ofbipartite decompositions (MEBD). Big MEBD means that the system may not bedecomposed into two weakly entangled subsystems. MEBD allows one to define, forinstance, whether the given quantum system may be a candidate for a quantumregister, where the above decomposition is undesirable.  A method of lower estimation of MEBD is represented. Examples of big MEBD inspin-1/2 chains governed by the $H_{dz}$ Hamiltonian in the strong externalmagnetic field are given.
