The behaviors of the spin-wave excitations around the ferromagnetic impurities in the two-dimensional spin-1/2 Heisenberg antiferromagnets are investigated for the cases with one, two and four impurities respectively. By means of the double-time Green's function numerical procedure, it is found that, in the two impurity case, two ferromagnetic impurities prefer to form an effective singlet. While in the four impurity case we obtained that, two nearest-neighbor ferromagnetic domains with contrary spin directions are formed in the antiferromagnetic background, and thus the whole system has the lowest energy.

In this chapter we give several examples of how the multiscale approach for atomistic spin-dynamics, as described in Part I and Part II of this book, performs for describing magnon excitations of solids. Due to the recent experimental advancements in detecting such excitations for surfaces and multilayers, we focus here primarily on spin wave excitations of two-dimensional systems. The discussion can easily be generalized to bulk magnets, and in fact some examples of bulk properties are given in this chapter as well. Magnons can be categorized as dipolar and exchange magnons, where the latter are in the range of giga Hz frequency, and are the main focus of this chapter.
