Malik, S.V.; Dias, E.T.; Nigam, A.K.; Priolkar, K.R. (Journal of Physics D: Applied Physics. 55(16); 2022; ArticleID_165002.)

A systematic study of crystal structure, local structure, magnetic and transport properties in quenched and temper annealed Ni sub(2-x) Mn sub(1+x) Sn alloys indicate the formation of Mn sub(3) Sn type structural defects ...
Multifunctional plasmonic nanomaterials (Chapter 13)

Sudhir, C. (Fundamentals and Properties of Multifunctional Nanomaterials, Ed. by Sabu Thomas, Nandakumar Kalarikkal and Ann Rose Abraham. 2021; 297-330.)

Plasmonic nanomaterials are promising candidates for numerous applications including chemical and biological sensing, surface-enhanced processes, and nanoscale optoelectronic devices. Their unique optical properties have ...
Local structural evolution in the anionic solid solution Zn Se sub(x) S sub(1-x)

Dan, T.; Mohanty, A.; Dutta, A.; Varma, R.M.; Sarkar, S.; Marco, I.D.; Eriksson, O.; Welter, E.; Pollastri, S.; Olivi, L.; Priolkar, K.R.; Sarma, D.D. (Physical Review B. 104(18); 2021; ArticleID_184113.)

The century-old Vegard's law has been remarkably accurate in describing the evolution of the lattice parameters of almost all solid solutions. Contractions or expansions of lattice parameters of such systems depend on the ...
Kinetic arrest of the ferromagnetic state in Mn sub(3) GaC and Ni sub(2) MnGa composite mixtures

Priolkar, K.R.; Nevgi, R.; Dias, E.T.; Nigam, A.K. (Scientific Reports. 11; 2021; ArticleID_19588.)

The kinetics of the ferromagnetic to antiferromagnetic transition in Mn sub(3) GaC can be arrested and its magnetic properties can be tuned by mixing a small amount (approx. 10 percent) of Heusler Ni sub(2) MnGa to Mn ...

We report enhanced Na0ion conductivity of Na sub(3+x) Sc sub(x) Zr sub(2-x) Si sub(2) PO sub(12) (x = 0.2-0.5), prepared through solid-state reaction method with optimized sintering temperature of 1220 degrees C for 15 h. ...
Structural defects responsible for the strain glassy transition in Ni sub(50+x) Ti sub(50-x)

Nevgi, R.; Pollastri, S.; Aquilanti, G.; Priolkar, K.R. (Physical Review B. 103(6); 2021; ArticleID_064108.)

The strain glassy phase is produced by doping a small percentage of impurity in a martensitic alloy. Its ground state is conceived to consist of martensitic nanodomains spatially separated from each other by a defect phase. ...
