Amorphous magnetism

For a two-sublattice antiferromagnet, one simply has two coupled single-ion equations such as Equation (15) that are simultaneously solved selfconsistently for the two sublattice average moments. A p-sublattice material gives rise to p coupled equations and presents no special difficulty. The MFT method has been generalized to random, disordered, and amorphous magnetic materials by Rancourt et al. (1993).

Heating MnCu(opba)(DMSO)3 to 140° under vacuum results in a product of which the stoichiometry is MnCu(opba) 0.7DMSO. This product behaves as an amorphous magnet below = 6.5 K. 

Further improvements in the frequency response of thin film heads have been investigated by preparing multilayered films with insulating (Si02) interlayers (Louis, Jeong Walser, 1990), or with heteroamorphous structures, where amorphous, magnetic nanoparticles ( 5 nm) are scattered...

On removal from solution and exposed to air, crystalline MOROF-l loses guest solvent molecules very rapidly, becoming an amorphous magnet with a lower critical temperature (Fig. 19b). The critical temperature is determined not only by the...

There would seem, therefore, to be a fruitful field of research in further study of the preparation-dependent properties of amorphous magnetic films. He shows that some results reported in his paper support this view. Cargill (1978b), for...
