Canted magnetic moments

Kagome lattice leads to Dzyaloshinsky-Moriya (DM) interactions, the in-plane components of which can give rise to magnetic polarizations in the out-of-plane directions with canted vectors of magnetic moments.16 It is interesting to... 

Neutron diffraction, magnetization and Mossbauer data by Bazela et al. (1981a) show a transition to a ferrimagnet with canted moments. The angle between the magnetic moment direction and the c-axis of the Ni2In-type structure is 34° 4°. 

More detailed study of the magnetic moments and internal magnetic fields of the two iron sites in FeaP suggests that it is ferromagnetically ordered, rather than ferrimagnetically with spin canting [108].

The Mn-Mn separation in DyMn2 is exactly at its critical value. In consequence, it was shown by neutron diffraction (Ritter et al. 1991) that below the Curie temperature of Jc=45K only one out of four (of the crystallographic equivalent) Mn atoms possess a magnetic moment (fiua = 1-4/4b). These spins are ferromagnetically ordered. The Dy sublattice forms a spin-canted FM structure with /toy = 8.8/tB. The Mn atoms that... 

In the whole range of oxygen content, Pr samples are insulators with a strong hybridization of the 4f bands with the 2p oxygen and the 3d copper bands. Boothroyd et al. (1997) have shown - based on neutron single-crystal diffraction - that the magnetic moments (/,t = 0.56 ttH forx = 7 and 1.15/,tB forx = 6) are canted. 

If complete compensation of differently oriented magnetic moments is not possible, canted or helical spin arrays may be formed. Similar to ferrimagnetism. there is a small resulting ferromagnetic moment for T<0. . rir. Fig. 11. Often the magnetization is field dependent according to...
