Magnetic skin effect in Pb(FeNb)O
N. Giles-Donovan, A. D. Hillier, K. Ishida +9
Relaxor-ferroelectrics display exceptional dielectric properties resulting from the underlying random dipolar fields induced by strong chemical inhomogeneity. An unusual structural…
Effect of random antiferromagnetic exchange on the spin waves in a three-dimensional Heisenberg ferromagnet
S. Hameed, Z. Wang, D. M. Gautreau +12
Neutron scattering is used to study spin waves in the three-dimensional Heisenberg ferromagnet YTiO, with spin-spin exchange disorder introduced La-substitution at the Y…
Two-dimensional ferromagnetic spin-orbital excitations in the honeycomb VI
H. Lane, E. Pachoud, J. A. Rodriguez-Rivera +6
VI is a ferromagnet with planar honeycomb sheets of bonded V ions held together by van der Waals forces. We apply neutron spectroscopy to measure the two dimensional (…
Growth and characterization of large (Y,La)TiO and (Y,Ca)TiO single crystals
S. Hameed, J. Joe, L. R. Thoutam +12
The Mott-insulating rare-earth titanates (RTiO, R being a rare-earth ion) are an important class of materials that encompasses interesting spin-orbital phases as well as ferrom…
Dynamics and Structure of PMN and PZN
G. Shirane, Guangyong Xu, P. M. Gehring
A review is given of recent neutron and x-ray scattering studies of the lead-oxide perovskite relaxor systems Pb(Zn1/3Nb2/3)O3-xPbTiO3 and Pb(Mg1/3Nb2/3)O3-xPbTiO3. X-ray measureme…
Quantum Impurities in the Two-Dimensional Spin One-Half Heisenberg Antiferromagnet
O. P. Vajk, P. K. Mang, M. Greven +2
The study of randomness in low-dimensional quantum antiferromagnets is at the forefront of research in the field of strongly correlated electron systems, yet there have been relati…
Neutron Diffraction Study of the Irreversible R-MA-MC Phase Transition in Single Crystal Pb[(Zn1/3Nb2/3)1-xTix]O3
Kenji Ohwada, Kazuma Hirota, Paul W. Rehrig +5
Single crystals of the relaxor PZN-xPT display an enormously strong piezoelectric character. Recent x-ray scattering studies have revealed novel electric-field induced phase transi…
