Effects of nonmagnetic metal additives in metallic antiferromagnets on exchange bias
Marian Fecioru-Morariu, Syed Rizwan Ali, Cristian Papusoi +2
The effect of nonmagnetic metal additives in metallic antiferromagnets (AFMs) on the exchange bias (EB) has been investigated from a structural, magnetic and Monte Carlo simulation…
Dilution dependence of blocking temperature distribution in the exchange bias system CoO(111)/Co(111)
M. R. Ghadimi, M. Fecioru-Morariu, B. Beschoten +1
In epitaxially grown CoO(111)/Co(111) bilayers we have determined the blocking temperature distribution f(Tb), which is correlated with the antiferromagnetic domain size (z) distri…
Interplay of structural and electronic phase separation in single crystalline La(2)CuO(4.05) studied by neutron and Raman scattering
V. P. Gnezdilov, Yu. G. Pashkevich, J. M. Tranquada +7
We report a neutron and Raman scattering study of a single-crystal of La(2)CuO(4.05) prepared by high temperature electrochemical oxidation. Elastic neutron scattering measurements…
Phonon Raman scattering in LaMn1-xCoxO3 (x = 0, 0.2, 0.3, 0.4, and 1.0)
V. P. Gnezdilov, Yu. G. Pashkevich, A. V. Yeremenko +5
The Raman-active phonons in perovskite-like LaMn1-xCoxO3 (x = 0, 0.2, 0.3, 0.4, and 1.0) were studied by measuring Raman spectra at temperatures of 295 and 5 K. The changes in the…
Low Energy Singlets in the Excitation Spectrum of the Spin Tetrahedra System Cu_2Te_2O_5Br_2
P. Lemmens, K. Y. Choi, A. Ionescu +8
Low energy Raman scattering of the s=1/2 spin tetrahedra system Cu_2Te_2O_5Br_2 is dominated by an excitation at 18 cm^{-1} corresponding to an energy E_S=0.6Δ, with Δthe spin gap…
Charge kinks as Raman scatterers in quarter-filled ladders
E. Ya. Sherman, C. Ambrosch-Draxl, P. Lemmens +2
Charge kinks are considered as fundamental excitations in quarter-filled charge-ordered ladders. The strength of the coupling of the kinks to the three-dimensional lattice depends…
