Fig. 5. Computed map of the 77 current density calculated in the ipsocentric approach for pentalene optimised at the RHF/6-31G level [14c]. Arrows show the projection of the current density induced by unit perpendicular magnetic field in the plane 1 bohr above the molecule. The clockwise sense indicates paramagnetic (anti-Lenz) circulation.

Barium ferrite adequate for certain permanent magnet applications can be prepared from crude mineral iron oxide. A past interest in the material for perpendicular magnetic recording stimulated studies of a variety of chemical routes, including hydrothermal synthesis, to produce powders [12]. 

Figure 13 shows various types of spin-wave modes in long nanowires. In very thin nanowires, where R < Rcoh, curling-type modes can be ignored [55, 114], and the perpendicular magnetization components obey Mx =... 

Figure 19. Boundary conditions and exchange (a) hard-soft interface with common A, (b) interface between two ferromagnetic phases with different A, and (c) quasi-discontinuous magnetization due to strongly reduced exchange between grains I and II. Note that the perpendicular magnetization component m(x) can be interpreted as a magnetization angle.

De Jongh showed that in 2-D systems, spin-reduction can also be deduced from the perpendicular magnetic susceptibility7,269. The experimental value of xi extrapoled to 0 K is in good agreement with the theoretical value obtained by means of the spin-wave theory (Xi (0). The difference between the latter value and that calculated via the molecular field approach Xkmf) is essentially due to the zero-point spin reduction.
