Theoretical Investigation of Muon Trapping in the Chemical Ferromagnet 4-(p-chlorobenzylideneamino)-TEMPO
Abstract
When the muon is injected into a material, it interacts with the local magnetic fields in its environment. Theory can aid in interpreting experimental results by indicating the location of the muon or its hydrogenic counterpart, muonium. Furthermore, theoretical predictions of the hyperfine fields at the muon sites can lead to a prediction of the easy axis in a ferromagnetic material. The locations and hyperfine properties of the positive muon and muonium in ferromagnetic p-Cl-Ph-CH=N-TEMPO were studied via the first-principles Hartree-Fock technique. The two most likely candidates for explaining the experimental data were found to be a muon trapped at the chlorine site and a singlet muonium state at the radical oxygen. The direction of the easy axis was also determined.
