Keimer A high-resolution neutron spectroscopic technique is used to measure momentum-resolved magnon lifetimes in the prototypical two- and three-dimensional antiferromagnets Rb 2 MnF 4 and MnF 2 , over the full Brillouin zone and a wide range of temperatures. We rederived theories of the lifetime resulting fro... [Phys. Rev. Lett. 111, 017204] Published Wed Jul 03, 2013
