Growing and probing 2D van der Waals quantum materials, twisted heterostructures and correlated magnetic oxides, with low-temperature transport and magneto-optics.
I am an experimental condensed-matter physicist. My current work covers CVD/CVT growth of 2D van der Waals quantum materials, heterostructure assembly, device fabrication, electrical transport and magneto-optical Kerr effect measurements.
My PhD at the Saha Institute of Nuclear Physics, awarded the 2024 Best Thesis Award, examined exchange bias and magnetoresistance in perovskite oxides, rare-earth intermetallics and sputtered multilayers. I combined SQUID and PPMS measurements, structural analysis and Monte Carlo simulations to explain the results.
Schematic illustrations of the physics behind my work.
CVD/CVT growth, exfoliation, flake transfer and stacking of heterostructures and twisted bilayers; moiré physics and device fabrication.
Giant exchange bias in perovskite oxides, spin-compensated systems and sputtered multilayers, supported by Monte Carlo theory.
Extraordinary and giant magnetoresistance in rare-earth aluminides such as GdFe2Al10 and DyFe2Al10.
Ionic engineering and protocols for boosting magnetic entropy change and relative cooling power.
Disorder-driven Griffiths-like phases and charge localization in double perovskites and doped manganites.
Monte Carlo modelling, Python/Fortran analysis tools and LabVIEW instrument control.
