Abstract :
Muon spin relaxation (μSR) studies were conducted on the organic ferromagnet MnCu(obbz). 1H2O (Tc =14K), where the unpaired spins reside on d-orbitals only. The asymmetry vs. time data recorded between 5K and 65K under zero and longitudinally applied fields did not show oscillatory behaviour but indicated that the transition to the ordered state is almost complete. A fit based on a simple exponential depolarising function indicates spin fluctuations far above the Curie temperature.
