Stabilization of charge and orbital ordered states by antiferromagnetism in the A-site ordered YBaMn2O6
X. N. Zhang, K. -Y. Choi, P. Lemmens +2
We report on Raman scattering measurements of the A-site ordered YBaMn2O6 in the wide temperature range of 10-650K. Upon cooling almost all phonon modes show pronounced temperature…
Manganite charge and orbitally ordered and disordered states probed by Fe substitution into Mn site in LnBaMn1.96Fe0.04O5, LnBaMn1.96Fe0.04O6 and LnBaMn1.96Fe0.04O5.5 (Ln=Y, Gd, Sm, Nd, Pr, La)
A. I. Rykov, Y. Ueda, K. Nomura
The layered manganese oxides LnBaMn1.96Fe0.04Oy (Ln=Y, Gd, Sm, Nd, Pr, La) have been synthesized for y=5, 5.5 and 6. In the oxygen-saturated state (y=6) they exhibit the charge and…
Electron Spin Resonance across the Charge-ordering Transition in YBaMn2O6
D. Zakharov, J. Deisenhofer, H. -A. Krug von Nidda +3
We investigated the metal-ordered manganite system YBaMn2O6 using electron spin resonance (ESR) in the paramagnetic regime across the charge-ordering and structural phase transitio…
Weakly coupled quantum spin singlets in BaCrO
M. Kofu, J. -H. Kim, S. Ji +6
Using single crystal inelastic neutron scattering with and without application of an external magnetic field and powder neutron diffraction, we have characterized magnetic interact…
CaCrO3: an anomalous antiferromagnetic metallic oxide
A. C. Komarek, S. V. Streltsov, M. Isobe +13
Combining infrared reflectivity, transport, susceptibility and several diffraction techniques, we find compelling evidence that CaCrO3 is a rare case of a metallic and antiferromag…
Field dependence of the quantum ground state in the Shastry-Sutherland system SrCu(BO)
F. Levy, I. Sheikin, C. Berthier +5
We present magnetic torque measurements on the Shastry-Sutherland quantum spin system SrCu(BO) in fields up to 31 T and temperatures down to 50 mK. A new quantum phase…
