| Research Abstract |
Atomic magnetic moments have difficulty finding the stable configuration in many of the triangular-lattice magnets, and give rise to frustration effects. To characterize such behavior,"chirality"plays an important role in addition to the"magnetization"as in ordinary magnets. We have succeeded in growing single crystals of the conductive triangular-lattice magnet PdCrO2, and discovered an anomalous Hall effect ascribable to the chirality mechanism. In addition, we reveal giant magneto-resistance oscillations in both magnetic PdCrO2 and nonmagnetic PdCoO2, which are attributable to the Fermi surface effects.
