Direct observation of electronic domains in manganites by spatially resolved spectroscopy
D. D. Sarma, Dinesh Topwal, U. Manju +8
We use a spatially resolved, direct spectroscopic probe for electronic structure with an additional sensitivity to chemical compositions to investigate high-quality single crystal…
Multi-scale Phase Modulations in Colossal Magnetoresistance Manganites
K. H. Kim, M. Uehara, V. Kiryukhin +1
Extensive experimental results are presented on the multi-scale phase modulation phenomena observed in colossal magnetoresistance manganites. Two key types of phase inhomogeneities…
Dielectric signatures of lattice instabilities at 32K and 245K in (M=Cu,Ni) Cuprates and Nickelates
P. V. Parimi, N. Hakim, F. C. Chou +2
New dielectric transitions are observed at common temperatures 32K and 245K, in isostructural and that are signatures of local lattice…
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…
