Abstract
AbstractFullerene‐containing complexes of Mn12‐based single molecular magnets have been studied. It is confirmed that fullerenes have strong influence on the relaxation processes inside single molecular magnets. Notably, the hysteresis curves are found not to return to the initial point after 1 T to −1 T to1 T measurement cycle, but the magnetization progressively increases with each cycle. The effect is reproducible, and we call it “magnetization training” drawing an analogy with the “magnetic training” in exchange‐biased multilayers, but emphasizing that magnetization rather than coercivity is trained in our system. The effect is presumably due to magnetic ordering linked to orientational ordering of incorporated C60 molecules in magnetic field.magnified image
