      abstract     = {Mn2Sb is ferrimagnetic below its Curie temperature (TC) and
                      passes through a spin flip transition with decreasing
                      temperature. The Co substitution induces an additional
                      first-order phase transition from the ferrimagnetic (FRI) to
                      an antiferromagnetic (AFM) state. This phase transition is
                      connected to a sizable magnetocaloric effect (MCE). To
                      understand the underlying mechanisms, the temperature
                      dependence of structural and magnetic changes was analyzed.
                      At the same time, the influence of the Co substitution was
                      explored. Three Mn2−xCoxSb (x = 0.1, 0.15, 0.2) compounds
                      were synthesized by cold crucible induction melting. Neutron
                      powder diffraction was performed to determine the magnetic
                      structures and to obtain the individual magnetic moments on
                      both symmetrically independent Mn sites. In combination with
                      the temperature-dependent magnetization measurements, the
                      magnetic phase transition temperatures were identified. In
                      the low-temperature range, additional antiferromagnetic
                      peaks were detected, which could be indexed with a
                      propagation vector of (0 0 ½). In Mn1.9Co0.1Sb at 50 K and
                      in Mn1.8Co0.2Sb at 200 K, a co-existence of the FRI and the
                      AFM state was observed. The pure AFM state only occurs in
                      Mn1.8Co0.2Sb at 50 K.},
