Size-induced Exchange Bias in Single-phase CoO Nanoparticles
Vikash Sharma, Sudip Pal, Divya Sharma +3
We report exchange bias (EB) in single-phase CoO nanoparticles, where two magnetic phases naturally emerge as the crystallite size decreases from 34.6 to 10.8 nm. The Néel temperat…

Ultrafast Carrier Relaxation and Second Harmonic Generation in a Higher-Fold Weyl Fermionic System PtAl
Vikas Saini, Ajinkya Punjal, Utkarsh Kumar Pandey +10
In topological materials, shielding of bulk and surface states by crystalline symmetries has provided hitherto unknown access to electronic states in condensed matter physics. Inte…
