Intrinsic avalanches and collective phenomena in a Mn(II)-free radical ferrimagnetic chain

E. Lhotel, D. B. Amabilino, C. Sporer +3

Magnetic hysteresis loops below 300 mK on single crystals of the Mn(II) - nitronyl nitroxide free radical chain (Mn(hfac)_2({\it R})-3MLNN) present abrupt reversals of the magnetiz…
