Cobalt oxide, as one of the most fascinating examples of correlated electronic system,
exhibits several exotic transport characteristics, such as superconductivity, charge ordering …

The layered cobaltite [Ca 2 CoO 3] 0.62 [CoO 2], often expressed as the approximate
formula Ca 3 Co 4 O 9, is a promising candidate for efficient oxide thermoelectrics, but an …

In frustrated magnetic systems, the competition amongst interactions can introduce
extremely high degeneracy and prevent the system from readily selecting a unique ground …

A noncoplanar spin ordering and a topological Hall effect (THE) may appear in triangular
lattice systems with 3/4-filling bands due to the nesting of the Fermi surface. One possible …

Attempts to unravel the nature of magnetic ordering in LaSrCoO 4 (Co 3+), a compound
intermediate between antiferromagnetic (AFM) La 2 CoO 4 (Co 2+) and ferromagnetic (FM) …
