Title Hysteresis in the spin transition regime of [Fe(NH2trz)3](NO3)2 as probed by ZF-μSR
Abstract The thermal spin transition which occurs in the polymeric chain compound [Fe(NH2trz)3](NO3)2 above room temperature has been investigated by zero-field muon spin relaxation (muSR) (~8-402 K). The depolarization curves are best described by a Lorentzian and a Gaussian line that represent fast and slow components respectively. The spin transition is associated with a hysteresis loop of width deltaT = 34K (T(up) = 346K and T(down) = 312 K) that has been delineated by the temperature variation of the initial asymmetry parameter. Comparison of zero-field and transverse field (20 Oe) muSR measurements shows that diamagnetic muon species occur over the entire temperature range, a large fraction of muons being however paramagnetic.
