Spin correlations in LSCO have been studied by neutron scattering. The commensurate antiferromagnetic order of the parent compound persists on a very short range up to a Sr content of x=0.3, whereas...
Berggold, K., Kriener, M., Becker, P., Benomar, M., Reuther, M., Zobel, C., ...
We present a combined study of the thermal expansion and the thermal conductivity of the perovskite series RCoO_3 with R = La, Nd, Pr and Eu. The well-known spin-state transition in LaCoO_3 is...
Anisotropic Susceptibility of La_2-xSr_xCoO_4 related to the Spin States of Cobalt (2008)
Hollmann, N., Haverkort, M. W., Cwik, M., Benomar, M., Reuther, M., Tanaka, A., ...
We present a study of the magnetic susceptibility of La_2-xSr_xCoO_4 single crystals in a doping range 0.3=0.5. This includes the pronounced kinks observed in the inverse magnetic susceptibility,...
Senff, D., Schumann, O., Benomar, M., Kriener, M., Lorenz, T., Sidis, Y., ...
The magnetic correlations in the charge- and orbital-ordered manganite La(0.5)Sr(1.5)MnO(4) have been studied by elastic and inelastic neutron scattering techniques. Out of the well-defined CE-type...
Mott-Hubbard versus charge-transfer behavior in LaSrMnO4 studied via optical conductivity (2007)
Gössling, A., Haverkort, M. W., Benomar, M., Wu, H., Senff, D., Möller, T., ...
Using spectroscopic ellipsometry, we study the optical conductivity sigma(omega) of insulating LaSrMnO4 in the energy range of 0.75-5.8 eV from 15 to 330 K. The layered structure gives rise to a...

Spin-wave dispersion in orbitally ordered La(0.5)Sr(1.5)MnO(4) (2005)
Senff, D., Krueger, F., Scheidl, S., Benomar, M., Sidis, Y., Demmel, F., ...
The magnon dispersion in the charge, orbital and spin ordered phase in La(0.5)Sr(1.5)MnO(4) has been studied by means of inelastic neutron scattering. We find an excellent agreement with a magnetic...
Spectroscopy of stripe order in La1.8Sr0.2NiO4 using resonant soft x-ray diffraction (2005)
Schuessler-Langeheine, C., Schlappa, J., Tanaka, A., Hu, Z., Chang, C. F., Schierle, E., ...
Strong resonant enhancements of the charge-order and spin-order superstructure-diffraction intensities in La1.8Sr0.2NiO4 are observed when x-ray energies in the vicinity of the Ni L2,3 absorption...
