    In the given contribution, the production of shape-memory glass-coated microwires based on Ni2FeZ (Z = Ga, Sn, Sb) and Co2Cr(GaSi) alloys is shown, focusing to their repeatable production. Such wires are characterized by monocrystalline structure along entire length. This leads to 1.5% reversible temperature shape memory effect for Ni2FeGa microwire in the as-cast state without necessity of additional thermal treatment. Moreover, well defined anisotropy results in the variation of permeability up to 550% during the phase transition. On the other hand, Co2Cr(GaSi) microwires show reversible superelastic straining up to 1.1% with a very small irreversible strain (<0.1%). •Ni2FeZ and Co2Cr(GaSi) glass-coated magnetic microwires were produced.•They are characterized by monocrystalline structure along entire length.•Ni2FeGa microwire exhibit 1.5% reversible temperature shape memory effect without necessity of thermal treatments.•Co2Cr(GaSi) microwire shows reversible superelastic straining up to 1.1%.
