mu SR study of the nitronyl nitroxide p-CNPNN
We present the results of a muon-spin rotation/relaxation (mu SR) study in zero and longitudinal magnetic fields and temperatures down to 40 mK of para-cyanophenyl nitronyl nitroxide (pCNPNN). This layered material is expected to show ferromagnetic interactions on the basis of susceptibility measure...

description | We present the results of a muon-spin rotation/relaxation (mu SR) study in zero and longitudinal magnetic fields and temperatures down to 40 mK of para-cyanophenyl nitronyl nitroxide (pCNPNN). This layered material is expected to show ferromagnetic interactions on the basis of susceptibility measurements. In a zero-field mu SR experiment, the spins of muons which are implanted in diamagnetic states will precess in any local internal fields. Bence a study of precession frequencies and/or relaxation rates can be used to follow the magnetic order parameter as a function of temperature. We find strongly temperature dependent muon relaxation below similar to 0.17K similar to that found recently in 1-NAPNN, indicating a magnetic transition at this temperature. |
