Highly Degenerate Canted Spin Structure in Bilayer Manganite La$_{1.1}$Sr$_{1.9}$Mn$_2$O$_7$ (2001)

Kubota, M., Oohara, Y., Yoshizawa, H., Fujioka, H., Hirota, K., Moritomo, Y., ...

We have examined magnetic ordering of the two-dimensional (2D) bilayer manganite La$_{1.1}$Sr$_{1.9}$Mn$_2$O$_7$ with neutron diffraction technique. Due to the two-dimensionality, there appears...

Influence of Quasi-Bi-Stripe Charge Order on the Resistivity and Magnetism in a Bilayer Manganite La$_{2-2x}$Sr$_{1+2x}$Mn$_{2}$O$_{7}$ (2000)

Kubota, M., Oohara, Y., Yoshizawa, H., Fujioka, H., Shimizu, K., Hirota, K., ...

The charge ordering in the bilayer manganite system La$_{2-2x}$Sr$_{1+2x}$Mn$_{2}$O$_{7}$ with $0.30 \le x \le 0.50$ has been studied by neutron diffraction. The charge order is characterized by the...

Charge and spin ordering in Nd{1/3}Sr{2/3}FeO{3} (2000)

Kajimoto, R., Oohara, Y., Kubota, M., Yoshizawa, H., Park, S. K., Taguchi, Y., ...

We have investigated the charge and spin ordering in Nd{1/3}Sr{2/3}FeO{3} with neutron diffraction technique. This sample undergoes a charge ordering transition accompanying charge disproportionation...

Anomalous ferromagnetic spin fluctuations in an antiferromagnetic insulator Pr_{1-x}Ca_{x}MnO_{3} (1998)

Kajimoto, R., Kakeshita, T., Oohara, Y., Yoshizawa, H., Tomioka, Y., Tokura, Y.

The high temperature paramagnetic state in an antiferromagnetic (AFM) insulator Pr_{1-x}Ca_{x}MnO_{3} is characterized by the ferromagnetic (FM) spin fluctuations with an anomalously small energy...
