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.
Graphical abstractMuon spin relaxation has been used to probe the paramagnetic to antiferromagnetic phase transition in manganese hydroxy squarate, Mn2(OH)2(C4O4). This confirms that the ordering temperature is 12.5 K and shows that there is significant short range order well above Tc.Figure optionsDownload full-size imageDownload as PowerPoint slide
