In this paper, surface plasmon resonance (SPR) sensor on 2D materials such as MoS{sub 2} and graphene on Au and magnetic material Ni in Kretschmann configuration is analyzed using transfer matrix method. Here we noted that by sandwiching the MoS{sub 2} layer between the Au and Ni film and adding graphene over Ni film improved the sensitivity as high as 229°/RIU. We also noted that the sensitivity of the proposed sensor changes with the addition of no. of layers of graphene and MoS{sub 2}. We expect that such a high sensitivity SPR sensor could find optional application in chemical examination, medical diagnostic and biological detections.
