Abstract
Spin-wave resonance (SWR) is a newly emerged method for studying surface magnetic anisotropy and surface spin-wave modes in (Ga,Mn)As thin films. On the basis of recent SWR studies of (Ga,Mn)As thin films we show that the cubic surface anisotropy is an essential factor determining the configuration regions of existence of surface spin-wave modes. These proved to exist only for those directions of film magnetization that lie in the immediate vicinity of hard cubic anisotropy axes.

Thin films of pentacene of 32-nm thickness obtained by organic molecular beam depo- sition (OMBD) in high vacuum conditions onto silicon/native silica (Si/SiO2) and fused silica substrates were examined. Anisotropic opti...
On the closest distance between a point and a convex body / O najmniejszej odległości między punktem a ciałem wypukłym
On a strictly convex curve we find explicitly a point realizing the shortest distance to a given point lying in the exterior of our curve. The result uses a support function of a strictly convex plane curve and can have...
Some noncommutative rings constructed on the base of polynomials x² + tx + 1 and their zero divisors
For any Galois field F = GF(pn) we construct some ring extension R(F) of order p4n. Such construction may be applied also for any infinite field F with char F 6= 0. Then, for any element of R(F) we give necessary and suf...
Duality Principle for some σ-ideals of subsets of the real line / Zasada dualności dla pewnych σ- ideałów podzbiorów prostej rzeczywistej
In this note there is proved that a theorem analogous to Sierpinski-Erdös duality theorem for some σ -ideals of subsets of the real line and the family of sets of the first category on the real line is valid.
