Students who are willing to join the Spintronic Material and Device Lab for pursuing their PhD during July (2026) semester and who have submitted their application for PhD program at IIT Ropar, are encouraged to contact Dr. Debangsu Roy (debangsu@iitrpr.ac.in) through e-mail.
We are immediately looking for two PhD students willing to work in the following areas:
1: Unveiling Altermagnetic Order through Spin-Orbit Torque and Transport in Thin Film Devices
This project probes altermagnetism — a recently discovered class of collinear magnetic order that combines zero net magnetization with momentum-dependent spin-split bands, placing it at the intersection of quantum materials and spintronics. The student will fabricate thin-film and heterostructure devices to detect and control this hidden spin texture using spin-orbit torque generation, harmonic Hall transport, and symmetry-resolved electrical measurements. The work directly connects quantum-mechanical band-structure effects to measurable charge-to-spin conversion phenomena, offering a route to explore Berry-curvature-driven and time-reversal-symmetry-breaking transport at the nanoscale. Beyond fundamental discovery, altermagnets promise field-free spin-orbit torque switching and THz-frequency spin dynamics, positioning this work at the forefront of energy-efficient, non-volatile memory and neuromorphic computing applications.
2: Superconducting Resonators for Hybrid Quantum Systems
This project focuses on the design, fabrication, and characterization of high-quality-factor superconducting microwave resonators, structures that exploit macroscopic quantum coherence and the Meissner state to confine and manipulate photons with minimal dissipation. The student will work on planar resonator geometries, cryogenic microwave measurements, and coupling schemes relevant to circuit quantum electrodynamics, gaining hands-on exposure to quantum-coherent device physics rarely accessible outside dedicated quantum labs. The work bridges fundamental studies of two-level-system losses and quasiparticle dynamics with practical device engineering at millikelvin temperatures. These resonators are foundational building blocks for quantum sensing, parametric amplification, and hybrid magnon-photon or spin-photon coupling experiments, directly linking this project to emerging quantum information and quantum sensing technologies.
