Abstract

First-principles unrestricted Hartree-Fock theory is used to obtain the trapping sites for muon and muonium in ferromagnetic p-Cl-Ph-CH=N-TEMPO (4-(p-chlorobenzplideneamino)- 2,2,6,6-tetramethylriperidin-1-yloxyl) and the hyperfine interaction tensors for these sites. Using the calculated hyperfineinteractions to fit the two experimentally observed muon spin rotation frequencies, it has been concluded that the two most likely candidates for explaining the experimental data are a muon trapped at the chlorine site and asinglet muonium state at the radical oxygen. The direction of the easy axis is also determined. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
