Giant reversible magnetoresistance effect in a Ni46Co3Mn35Cu2In14 polycrystalline alloy
Source abstract
Abstract
In this work, the reversible magnetoresistance properties in a Ni46Co3Mn35Cu2In14 polycrystalline alloy were studied. By using Co substitution for Ni to improve the magnetic properties and Cu substitution for Mn to reduce the transformation hysteresis, large magnetic field dependence of the transformation temperature up to 6.8 K T−1 and low transformation hysteresis of 11.5 K were achieved. Such optimized magnetostructural transformation parameters allowed the complete and reversible magnetic field induced inverse martensitic transformation to be realized under the field of 5 T, giving rise to a giant reversible magnetoresistance of −73.5%.
