Key Points

To investigate the magnetoresistance and exchange-bias effects at the surface of NiS2 nanoflakes.
Conducted local transport measurements on nanoscale NiS2 flakes.
Performed magnetometry measurements to assess magnetic properties.
Observations indicated large giant magnetoresistance effects in NiS2 nanoflakes.
Found significant exchange-bias effects linked to the surface magnetic textures.

Implication

Local transport and magnetometry measurements reveal large magnetoresistance in NiS2 nanoflakes, suggesting potential applications.

Abstract

Local transport and magnetometry measurements on nanoscale flakes of NiS 2 have led to the discovery of large magnetoresistance and exchange-bias effects connected to surface magnetic textures in NiS 2 .
