Substituting Mn with small amounts of Co in Mn2Sb leads to kinetic arrest and magnetic frustration effects. By adding small amounts of In in place of Sb, the tetragonality and thereby the kinetic arrest properties can be modified and controlled. We investigate the kinetic arrest effect in Mn1.82Co0.18Sb1−xInx with x = 0 and 0.5 at the first-order antiferromagnetic-ferrimagnetic magnetostructural transition. Kinetic arrest is observed in both systems, whereby the arrest is partial under 5 T field for Mn1.82Co0.18Sb and full for Mn1.82Co0.18Sb0.95In0.05. The FI state remains arrested as long as the cooling-field is maintained. •The magnetic properties of Mn1.82Co0.18Sb1−yIny (y = 0, 0.05) were investigated.•The alloys show the first order AF-FI magnetostructural transition.•The magnetic SG behavior is observed in the alloy with In for the first time.•Full kinetic arrest of the FI state is observed in the alloy with In.•The KA states of the alloys prevail so long as the cooling field is maintained.
