Raman scattering study of vibrational and magnetic excitations in Sr${}_{2-x}$La${}_x$IrO${}_4$

H. Gretarsson, J. Sauceda, N. H. Sung +5

We have measured the doping and temperature dependence of lattice vibrations and magnetic excitations in the prototypical doped spin-orbit Mott insulator Sr${}_{2-x}$La${}_x$IrO${}_4$ (x…
