Local nematic susceptibility in stressed BaFe${}_2$As${}_2$ from NMR electric field gradient measurements

T. Kissikov, R. Sarkar, M. Lawson +10

The electric field gradient (EFG) tensor at the ${}^{75}$As site couples to the orbital occupations of the As p-orbitals and is a sensitive probe of local nematicity in BaFe${}_2$As$_2…
