Neutron-Irradiation Induced Magnetization and Persistent Defects at High Temperatures in Graphite
Ranjan Mittal, Mayanak K. Gupta, Sanjay K. Mishra +8
Structural as well as magnetization studies have been carried out on graphite samples irradiated by neutrons over 50 years in the CIRUS research reactor at Trombay. Neutron diffrac…
Spin-Phonon Coupling and Thermodynamic Behaviour in YCrO3 and LaCrO3: Inelastic Neutron Scattering and Lattice Dynamics
Mayanak K. Gupta, Ranjan Mittal, Sanjay K. Mishra +4
We report detailed temperature-dependent inelastic neutron scattering and ab-initio lattice dynamics investigation of magnetic perovskites YCrO3 and LaCrO3. The magnetic neutron sc…
Defect topology and annihilation by cooperative cascading movement of atoms in highly neutron irradiated graphite
Ranjan Mittal, Mayanak K. Gupta, Sanjay K. Mishra +10
Graphite has been used as neutron moderator or reflector in many nuclear reactors. The irradiation of graphite in a nuclear reactor results in a complex population of defects. Heat…
