Glassy Spin Freezing and Gapless Spin Dynamics in a Spatially Anisotropic Triangular Antiferromagnet Ag2MnO2

S. Ji, J. -H. Kim, Y. Qiu +6

Using elastic and inelastic neutron scattering techniques, we show that upon cooling a spatially anisotropic triangular antiferromagnet Ag${}_2$MnO${}_2$ freezes below $T_f\sim 50$ K…
