摘要：

We present the results of our theoretical analysis of magnetic, electric, and transport properties of domain walls in ferromagnets. The results were obtained within the semiclassical approximation and are valid for smooth domain walls. Taking into account Coulomb interaction between electrons, we calculated spin and charge accumulation at the wall. Local conductivity due to scattering from impurities located in the region of the domain wall was also calculated.
