The Exchange Bias effect in pure Co2C nanoparticles
Nirmal Roy, Md. Arif Ali, Arpita Sen +2
We study the low temperature magnetic properties of nanoparticles of pure transition metal carbide, viz., Co2C, with an average particle diameter of nm. These Co2C nano…
Localized spin waves at low temperatures in a Cobalt Carbide nanocomposite
Nirmal Roy, Arpita Sen, Prasenjit Sen +1
We study magnetic, transport and thermal properties of Cobalt carbide nanocomposite with a mixture of Co2C and Co3C phases in 1:1 ratio, with an average particle diameter of 40$\pm…
CrCTe: Computational design of a robust two-dimensional anti-ferromagnetic semiconductor
Satyananda Chabungbam, Prasenjit Sen
Using density functional theory calculations we establish the hitherto unknown compound CrCTe to be a stable anti-ferromagnetic semiconductor in the R crystal structur…
Peierls transition and edge reconstruction in phosphorene nanoribbons
Ajanta Maity, Akansha Singh, Prasenjit Sen
Atomic and electronic structures of phosphorene nanoribbons are studied within density functional theory. These novel materials present different physical phenomena expected in two…
Designing Fe Nanostructures at Graphene/h-BN Interfaces
Soumyajyoti Haldar, Pooja Srivastava, Olle Eriksson +2
Tailor-made magnetic nanostructures offer a variety of functionalities useful for technological applications. In this work, we explore the possibilities of realizing Fe nanostructu…
First-principles study of TMNan (TM= Cr, Mn, Fe, Co, Ni; n = 4-7) clusters
Kalpataru Pradhan, Prasenjit Sen, J. Ulises Reveles +1
Geometry, electronic structure, and magnetic properties of TMNan (TM=Cr-Ni; n = 4-7) clusters are studied within a gradient corrected density functional theory (DFT) framework. Two…
