Magnetic units

Furthennore, the magnetic diffraction and the nuclear diffraction do not interfere with one another, and the nuclear and magnetic intensities simply add together, although in many cases the magnetic unit cell is larger than the nuclear unit cell, which produces additional diffraction peaks.

In the present book, for magnetism we use the SI unit that is based on the MKS A (meter, kilogram, second, ampere) system. In accordance with that, the tesla (1T = 10" gauss) was presented as the magnetic unit in Chapter 17 (see Fig. 17.10a and b). It is useful to know both the SI and Gaussian systems and be able to convert between them. Thus, when one attempts to solve a magnetics problem, to avoid errors one is well advised to stick to a single convenient unit system. A useful conversion table of... 

An important characteristic of this material is the high spin value of the magnetic unit inside the chain (5 = 3). It is remarkable that with the small... 

FIGURE 2.14 The magnetic ordering in NiO. The Ni planes only are pictured, and alternate close-packed layers have opposing magnetic moments. Note that the magnetic unit cell length is double that of the normal unit cell.

Bold dashed lines indicate positions of domain walls, while bold solid lines outline a magnetic unit cell. The two-magnon Raman process is shown also bold arrows demonstrate spins on adjacent sites and curved lines indicate broken magnetic bonds. 

Measured moments can also be obtained at fixed external field with varying temperature, converted to M in emu/mol, and then to the intrinsic property of magnetic susceptibility from M at a low applied external field H, well below the saturation region the susceptibility x = Mj II. The present lack of standardized magnetic units is a frequent cause of frustration to those comparing magnetic measurement reports in the literature.45 Many X measurements are reported in units of emu/(Oe mol) or cm3/mol, which are (perhaps surprisingly) equivalent.
