Hill, Gang Cao, Robert M. Konik, and M. P. M. Dean We study the evolution of magnetic excitations in the disordered two-dimensional antiferromagnet Sr 2 Ir 1 − x Ru x O 4 . The maximum energy of the magnetic excitation remains robust up to x = 0.77 , with a gap opening at low dopings and increasing to over 150 meV at x = 0.77 . At these higher Ru concentrations, th… [Phys. Rev. B 95, 121103(R)] Published Mon Mar 06, 2017
