Surface magnetic susceptibility and relaxation of domain walls in yttrium orthoferrite
Krinchik G. S., Chepurova E. E., Shtain A. V.
Using a magnetooptical method, it is established that the surface magnetic susceptibility of domain walls in yttrium orthoferrite on the (001) face is several times higher than the magnetic susceptibility of walls in the bulk, while the relaxation frequency of the "additional" motion of domain walls in the layer near the surface is approximately three orders of magnitude smaller than the bulk frequency.
