摘要：
The organic magnetoresistive (OMAR) effect has been observed in many different organic semiconductors, whereas a corresponding effect has not been reported for inorganic ones. What property makes organics behave so differently regarding magnetotransport? By studying C-60 devices using several different electrode materials we show that C-60, unlike many other organic semiconductors, does not exhibit any intrinsic OMAR effect. However, we find that as soon as the carriers in C-60 are brought in proximity with hydrogen-containing compounds; either in the form of a polymeric electrode, or side-chain substituents, a weak OMAR effect is observed. This shows that hydrogen is crucial for the observation of OMAR. (c) 2007 Elsevier B.V. All rights reserved.
