Magnetic Properties of Some Fullerene Compounds

摘要

Magnetic properties of some fullerene intercalation compounds are detailed. A few examples are presented including properties of 1) Acceptors: MoF6From magnetic measurements the existence of positively charged C60(C60+) can be inferred 2) Donnors: YbxC60and Eu3C60compounds. Magnetic properties of (YbxC60) are dominated by crystal field effects. A high field magnetic transition (17 T at 4 K) occurs in Eu3C60associated with a large hysteresis of the magnetization and relaxation effects. This complex magnetic behaviour is attribued to Eu2+.
