  • Abstract
    We are dealing with the influence of Hopkinson effect on magnetocaloric effect in glass-coated Ni-Mn-In-Co microwires in the given contribution. We have shown that although the entropy change is smaller in low fields, the refrigerant capacity per unit of applied field is three times higher for low field (300 Oe) comparing to that of 30 kOe. This points to the fact that Hopkinson effect can be employed to increase the efficiency of magnetocaloric effect.
