Within the whole temperature range, the response of the sample consists of a magnetic and nonmagnetic contribution. At low temperatures, description of the magnetic part of the μSR signal requires a two-component relaxation function. For temperatures below 50 K, a well-defined frequency is observed for about 45% of the muons, while about 45% show a strong relaxation due to a broad static field distribution. This situation changes above 50 K, where only the strongly damped signal is observed in addition to the paramagnetic signal. The data were analyzed by the following functional form using the free software package MUSRFIT (38)Embedded Image(1)

Here, VM and V* denote the relative magnetic fraction of the oscillating and strongly damped magnetic signals, respectively. μ0Hint is the local internal magnetic field at the muon site. λT and λL are the depolarization rates representing the transversal and longitudinal relaxing components of the magnetic parts of the sample. λnm is the relaxation rate of the nonmagnetic part of the sample.
