Spin direction through ferromagnetic material

Click For Summary
SUMMARY

The spin direction of electrons in ferromagnetic materials can be either parallel or antiparallel, depending on the specific material and its properties. In ferromagnetic materials, the density of states at the Fermi level for parallel spin states is typically lower than that for antiparallel states. This relationship affects both the scattering rate and conductivity. For a comprehensive understanding, it is essential to consider the type of ferromagnetic material in question and its unique characteristics.

What is the spin direction of the electrons through the ferromagnetic material?
It will become parallel or antiparallel?
I was confused because the scattering rate and conductivity both depend on the density of state at Fermi level.
For ferromagnetic material, is it right to say that at the Fermi level the density of state of spin direction parallel is small than those in anti parallel?

You have to clarify what kind of ferromagnetic material is.
there is no common answer for such a question.

Give you a suggestion, please refer to the concept of spin valve.
