| Abstract: | Muon spin relaxation has been used to study the magnetic phase transition and spin dynamics above Tc in Mn2(OH)2(C4O4). These studies confirm previous findings of a transition to long range order, providing a more accurate determination of Tc = 12.5 K as well as indicating short range order at temperatures above the phase transition. The muon measurements are insensitive to the presence of a small quantity of manganese carbonate in the sample that tend to dominate bulk magnetic susceptibility experiments. |
