Antiferromagnetism in CaCuTiO studied by magnetic Raman spectroscopy
A. Koitzsch, G. Blumberg, A. Gozar +4
For CaCuTiO -- an insulator that exhibits a giant dielectric response above 100 K -- Cu antiferromagnetic spin ordering has been investigated by magnetic…
Enhancement of long-range magnetic order by magnetic field in superconducting La2CuO(4+y)
B. Khaykovich, Y. S. Lee, R. Erwin +5
We report a detailed study, using neutron scattering, transport and magnetization measurements, of the interplay between superconducting (SC) and spin density wave (SDW) order in L…
Ferroelectric Ordering in the Relaxor Pb(Mg1/3Nb2/3)O3 as Evidenced by Low-Temperature Phonon Anomalies
S. Wakimoto, C. Stock, R. J. Birgeneau +5
Neutron scattering measurements of the lowest-energy TO phonons in the relaxor Pb(Mg1/3Nb2/3)O3 (PMN) are reported for 10<=T<=750 K. The soft mode, which is overdamped by the polar…
Neutron Diffuse Scattering from Polar Nanoregions in the Relaxor Pb(Mg1/3Nb2/3)O3
K. Hirota, Z. -G. Ye, S. Wakimoto +2
We have studied the neutron diffuse scattering in the relaxor PMN. The diffuse scattering appears around the Burns temperature (~620K), indicating its origin from the polar nanoreg…
Soft Mode Dynamics Above and Below the Burns Temperature in the Relaxor Pb(Mg_1/3Nb_2/3)O_3
P. M. Gehring, S. Wakimoto, Z. -G. Ye +1
We report neutron inelastic scattering measurements of the lowest-energy transverse optic (TO) phonon branch in the relaxor Pb(Mg_1/3Nb_2/3)O_3 from 400 to 1100 K. Far above the Bu…
Diagonal static spin correlation in the low temperature orthorhombic Pccn phase of La1.55Nd0.4Sr0.05CuO4
S. Wakimoto, J. M. Tranquada, T. Ono +5
Elastic neutron scattering measurements have been performed on Nd, Sr co-doped La1.55Nd0.4Sr0.05CuO4, which exhibits a structural phase transition at Ts ~ 60K from the low temperat…
