High Temperature Charge-Ordering Fluctuation in Manganites
K. H. Kim, M. Uehara, S-W. Cheong
High temperature (T) studies of La_{1-x}Ca_{x}MnO_{3} show that charge and phonon transport is significantly suppressed in a narrow doping region of x~1/2 and in a wide T range up…

Charge and Spin Order in La2-xSrxNiO4 (x=0.275 and 1/3)
S. -H. Lee, S-W. Cheong, K. Yamada +1
We report polarized and unpolarized neutron diffraction measurements on La2-xSrxNiO4 (x=0.275 and 1/3). The data for the spin ordered states are consistent with a collinear spin mo…
