Thermomagnetic effect in a twisted carbon nanotube

A generation of magnetic field under application of thermal gradient in a twisted carbon nanotube (analog of Zavaritskii effect) is theoretically discussed. The analytical expression for twist angle dependence of the induced thermomagnetic field is obtained. The estimates of the model parameters sug...

Description
Summary:A generation of magnetic field under application of thermal gradient in a twisted carbon nanotube (analog of Zavaritskii effect) is theoretically discussed. The analytical expression for twist angle dependence of the induced thermomagnetic field is obtained. The estimates of the model parameters suggest quite an optimistic possibility to experimentally realize the predicted effect. ► Generation of magnetic field in twisted carbon nanotube under heat flux is discussed. ► Expression for twist angle dependence of induced thermomagnetic field is obtained. ► Estimates of model parameters suggest optimistic possibility to observe this effect.
