The Kagome lattice involves a triangle as a basic unit. On the triangle, the mechanism by Kumar and Shastry [18, 31] for the anomalous Hall effect will be available and explain the experiments by Wang et al. [Pg.210]

The Kagome lattice structure clearly explains the non-symmetric nature of the band structure of the C0O2 layer. When the effect of the Kagome lattice becomes dominant, the bottom band, i.e., the flat band as shown in Fig, 3(a) will play a crucial role on the electronic state. Mielke [32] has shown that the flat band with the Coulomb interaction has the ferromagnetic ground state at around half filling. A prospective system for the ferromagnet will be dl transition metal oxides, i.e., the layered titanates with iso-structure of the cobalt oxides. [Pg.210]

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... [Pg.402]

Incidentally, let us observe that the same exponents can be obtained with partially repulsive chains provided that the repulsive part is dominant. Thus, Watson21 showed that purely repulsive chains drawn on a honeycomb lattice can be transformed into chains drawn on the corresponding kagome lattice (see Fig. 4.2), in such a way that the interaction potentials for the new chains are...
