Unravelling magnetic vortex-like excitations through rapid thermal quenching in low-carbon steel Open
Steel, traditionally valued for its structural strength, emerges in this study as a remarkable material for exploring novel magnetic phenomena. We investigate how common processing techniques-thermal treatments and mechanical strain-signif…

Dimension-dependent critical scaling analysis and emergent competing interaction scales in a two-dimensional van der Waals magnet Open
We investigate thickness-dependent transformation from a paramagnetic to ferromagnetic phase in Cr$_{2}$Ge$_{2}$Te$_{6}$ (CGT) in bulk and few-layer flake forms. 2D Ising-like critical transition in bulk CGT occurs at $T_{c}$ = 67 K with o…

Probing the strongly correlated magnetic state of Co<sub>2</sub>C nanoparticles at low temperatures using <i>μ</i>SR Open
Co 2 C nanoparticles (NPs) are amongst transition metal carbides whose magnetic properties have not been well explored. An earlier study (Roy et al 2021 J. Phys.: Condens. Matter 33 375804) showed that a pellet made from Co 2 C NPs exhibit…

Probing the strongly correlated magnetic state of Co$_2$C nanoparticles at low temperatures using $μ$SR Open
Co$_2$C nanoparticles (NPs) are amongst transition metal carbides whose magnetic properties have not been well explored. A recent study by Nirmal Roy et al. [1] showed that a collection of Co$_2$C NPs exhibit an exchange bias (EB) effect b…

Macroscopic, layered onion shell like magnetic domain structure generated in YIG films using ultrashort, megagauss magnetic pulses Open
Study of the formation and evolution of large scale, ordered structures is an enduring theme in science. Generation, evolution and control of large sized magnetic domains are challenging tasks, given the complex nature of competing interac…

Exploring the non-equilibrium fluctuation relation for quantum mechanical tunneling of electrons across a modulating barrier Open
We experimentally explore the phenomenon of electron tunneling across a modulated tunneling barrier which is created between an STM tip and an Au film deposited on a vibrating piezo surface. Measurements of the time series of the quantum m…

Exploring Large Chiral Domain Patterns Generated in Fe<sub>2</sub>O<sub>3</sub> Films with High Intensity Laser Induced Giant Magnetic Field Pulse Open
We report the observation of magnetic domain formation and reorientation in a Fe 2 O 3 magnetic tape by intense laser induced high magnetic field.Earlier reports have shown that high intensity lasers (femtosecond, terawatt) can create rela…
