Interplay between structure and magnetism in the low-dimensional spin system

Probing the interplay between crystal structure, magnetism and ion dynamics in new multinary oxides through the Rietveld refinement of high-resolution powder synchrotron and neutron diffraction data has becoming increasingly critical for the advancement of science and technology in condense matter science. Operando monitoring and deciphering the real-time (in-situ) chemical or structural changes, magnetic phase transitions complemented with electrochemical characterizations in series of novel framework framework materials will be presented. Focus will be in illustrating as how by changing the lattice dimensionality influence dramatically the thermodynamic properties by concerted study of specific heat, magnetic susceptibility, structural / magnetic phase transitions and allied spin fluctuations particularly at low temperature. Finally, the experimental data fitting using various theoretical models incorporating both the simulated structural and spin lattice interactions model will be justifiably analysed. Importance of Rotor molecules with drastic conductivity increase at the onset of phase transition will also be exemplified for its application in energy storage devices. In the last segment of the talk, Dr. Ali will brief the importance of Metal Organic Framework (MOFs /ZIFs) based mix matrix membranes for their potential application in the field of H2 storage and as a monovalent selective cation exchange membrane. The talk will highlight the brief summary of the (X+n) results collected so far in collaboration with beamline scientist at large scale synchrotron and neutron diffraction facilities worldwide.
