NORMAL SPIN-WAVE MODES OF COMPLEX EXCHANGECOUPLED CRYSTALS.
Abstract
Recently, a spin-wave theory has been constructed of the Holstein-Primakoff type applicable to exchange-coupled crystals with an arbitrary number of magnetic ions per primitive magnetic unit cell. In the present report, a simple, explicit, and general procedure is given for finding a complete set of normal spin-wave modes within the context of the above theory. A comparison of our procedure with the corresponding one of Wallace reveals that the present method is considerably easier to apply than his in practical computations involving an extensive class of complex exchange-coupled spin structures.
