Valence changes associated with the metal-insulator transition in BiLaNiO
H. Wadati, M. Takizawa, T. T. Tran +9
Perovskite-type BiNiO is an insulating antiferromagnet in which a charge disproportionation occurs at the Bi site. La substitution for Bi suppresses the charge disproportionati…
A `checkerboard' electronic crystal state in lightly hole-doped Ca_{2-x}Na_{x}CuO_{2}Cl_{2}
T. Hanaguri, C. Lupien, Y. Kohsaka +5
The phase diagram of hole-doped copper oxides shows four different electronic phases existing at zero temperature. Familiar among these are the Mott insulator, high-transition-temp…
NMR characterization of spin-1/2 alternating antiferromagnetic chains in the high-pressure phase of (VO)2P2O7
J. Kikuchi, K. Motoya, T. Saito +2
Local-susceptibility measurements via the NMR shifts of P and V nuclei in the high-pressure phase of (VO)PO confirmed the existence of a unique alte…
Spin-Trimer Antiferromagnetism in LaCuMoO
Y. Qiu, C. Broholm, S. Ishiwata +4
LaCuMoO is a cluster antiferromagnet where copper spin-1/2 form a network of st rongly coupled spin-trimers. The magnetic properties of this material have bee n exam…
Magnetic Susceptibilities of Spin-1/2 Antiferromagnetic Heisenberg Ladders and Applications to Ladder Oxide Compounds
D. C. Johnston, M. Troyer, S. Miyahara +11
A comprehensive theoretical and experimental study is presented of the magnetic susceptibility versus temperature χ(T) of spin S = 1/2 two- and three-leg Heisenberg ladders and lad…
