In ferromagnetic insulator, spin current flows when a temperature gradient is applied across the sample, which is detected by using ISHE in the paramagnetic sample. But i want to know the mechanism of spin current flowing in the sample.

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
