  • Probing electron-phonon coupling in magnetic van der Waals material NiPS3: a non-magnetic site-dilution study 
    PISTAWALA, NASHRA; KUMAR, ANKIT; Negi, Devesh; ROUT, DIBYATA; HARNAGEA, LUMINITA; Saha, Surajit; SINGH, SURJEET (IOP Publishing, 2024-04)
    NiPS3 is a Van der Waals antiferromagnet which has been shown to exhibit spin-phonon and spin-charge coupling in the antiferromagnetically ordered state below TN = 155 K. It is also a rare Ni-based negative charge-transfer-type ...
  • Magnetic excitation–phonon coupling in NiPS3 at high temperatures 
    Negi, Devesh; Badola, Shalini; Paul, Suvodeep; PISTAWALA, NASHRA; HARNAGEA, LUMINITA; Saha, Surajit (American Physical Society, 2024-09)
    The dynamics of coupled quasiparticle excitations can be crucial for understanding and engineering the novel states of matter, e.g., two-dimensional (2D) magnetic materials. NiPS3 is one of the 2D van der Waals antiferromagnets ...
