To the Editor

We agree with Boehme and Lupton1 that the organic spintronics community should focus more on scrutinizing the existing models and to carry out detailed spectroscopic experiments. However, there are other elements to take into consideration. In addition to distinguishing whether the bipolaron model or polaron-pair model applies when interpreting the magnetotransport properties of organic materials, another important task is to identify the contributions of the factors that cause spin relaxation, that is, the hyperfine field and spin–orbit coupling. The hyperfine field is considered the dominant factor, due to the lack of heavy atoms and the presence of hydrogen in organic materials2. However, spin–orbit coupling too is found to be a significant source of spin relaxation3.
