Outline of Final Research Achievements |
We have studied the microscopic origin of nuclear quadrupole resonance frequencies through the separation of the electric field gradient obtained in the electronic structure calculation and the analysis of the external parameter dependence. Particularly, in SmB6, the electric field gradients are separated for two components from the inside of MT (muffin-tin) sphere and the outside. Then, the microscopic origin of the pressure dependence has been studied. In parallel, the influence on the electric field gradient due to the mass correction effect in the spin-orbit coupling has been studied, quantitatively. In addition, the calculations of the electric field gradient for many compounds have been carried out. Now, it is progressing to a unified understanding of the microscopic origin of the electric field gradient.
