Current Research

• Anjan’s research interests are in investigating and harnessing emergent topological and quantum phenomena at the surfaces and interfaces of ultrathin or quasi two-dimensional materials and heterostructures. Examples include chiral spin textures, correlated spin- and charge-ordered states, topological surface states, superconductivity, collective excitations etc.
• Anjan leads a cross-institutional materials and device physics team on Spin Technology for Electronic Devices (SpEED). His team develops wafer-scale thin films and heterostructures using physical vapour deposition techniques and fabricates associated nanodevices using lithographic tools.
• Anjan’s team uses an array of in-house and facility-based materials and device characterizing techniques, including:
  • Magnetometry and transport using electrical and thermal probes
  • Microscopy with scanning probes (AFM/MFM, STM), electrons (TEM, holography), X-rays (TXM/XMCD), and light (Polar MOKE)
  • Spectroscopy using tunnelling, microwave transmission, and optical scattering modalities
• His recent research has focussed on spin topology – including magnetic skyrmions and topological materials.
