Times Cited Count：13 Percentile：60.62(Physics, Multidisciplinary)We report on the results of angle-resolved photoemission experiments on a quasi-one-dimensional -chain compound [Ni(chxn)Br]Br (chxn = 1
,2-cyclohexanediamine), a one-dimensional Heisenberg system with 
and 
K, which shows a gigantic non-linear optical effect. A "band" having about 500meV energy dispersion is found in the first half of the Brillouin zone 
, but disappears at 
. Two dispersive features, expected from the spin-charge separation, as have been observed in other quasi-one-dimensional systems like SrCuO, are not detected. These characteristic features are well reproduced by the - chain model calculations with a small charge-transfer energy 
compared with that of one-dimensional Cu-O based compounds. We propose that this smaller is the origin of the absence of clear spin- and charge-seperation in the photoemission spectra and strong non-linear optical effect in [Ni(chxn)Br]Br.

Times Cited Count：1 Percentile：7.78(Physics, Condensed Matter)We have performed angle resolved photoemission experiments on heavy-fermion compounds CeRhIn and CeIrIn. The obtained spectra are compared with the results of the full-potential linear-augmented-plane-wave (FLAPW) band-structure calculations, treating the Ce 4
electrons as being itinerant. The spectral contributions from the ligand Rh, Ir or In states were well reproduced by the calculations, although the features originated from Ce 4 states near 
were not clearly observed.
