Orbital-moments’ segregation Lr makes ‘orbital glass’ (OG). Covalent interactions Γk of Galois-group elements (GG-j) (j = x, y, z = 1, 2, 3) express by elementary excitations Eq in j-domain (GG-j). Connection Eq with phonons renormalizes sound frequency ωk (functional Δωk (Eq) is added). Wall between domains (j = y, z) with thickness δW=(Γ/K)1/2 and energy EW=(ΓK)1/2 is determined by constant K of j-domain anisotropy. Wall mass (mWEW) and its stabilization PW give oscillation spectrum EW(Wij). It may be used as non-ferromagnetic sonars.

Key words: orbital-moments’ segregation, orbital glass (OG), oscillations of OG-j-domains and walls (Wij) between them, non-ferromagnetic sonars.
