单分子器件中声子辅助和磁场诱导的近藤隧穿

Phonon-assisted and magnetic field induced Kondo tunneling in single molecular devices

K. Kikoin, M. N. Kiselev

摘要:

研究了低能单重态-三重态自旋带隙的磁性分子复合物中多声子发射/吸收过程引起的近藤隧穿,并表明通过改变激发三重态的塞曼分裂可以改变辅助声子的数目.结果表明,多声子近藤共振的结构可以通过磁场调谐来扫描。

英文摘要:

We consider the Kondo tunneling induced by multiphonon emission/absorption processes in magnetic molecular complexes with low-energy singlet-triplet spin gap and show that the number of assisting phonons may be changed by varying the Zeeman splitting of excited triplet state. As a result, the structure of multiphonon Kondo resonances may be scanned by means of magnetic field tuning.
