Abstract

The magnetic, magneto-transport and magnetocaloric properties of antiferromagnetic intermetallic compound NdCo2Si2(TN=32K) have been studied. The compound yields a positive magnetoresistance (MR) of about ∼123% at ∼5K in 8 T magnetic field. The MR value is significantly large vis – a – vis earlier reports of large MR in intermetallic compounds, and possibly associated with the changes in magnetic structure of the compound. The large MR value can be explained in terms of field induced pseudo-gaps on Fermi surface.
