Spin Order and Excitations in Triangular Antiferromagnet La2Ca2MnO7
Wei Bao, Y. X. Wang, Y. Qiu +6
We report a spin S = 3/2 triangular antiferromagnet with nearest-neighbor coupling J = 0.29 meV in La2Ca2MnO7. A genuinely two-dimensional, three-sublattice order develops below 2.…
Phonon softening and "forbidden" mode observed by Raman scattering in Na0.5CoO2
Q. M. Zhang, M. an, S. K. Yuan +6
Polarized Raman scattering measurements have been performed on Na0.5CoO2 single crystal from 8 to 305 K. Both the A1g and E1g phonon modes show a softening below Tc1 ~ 83 K. Additi…
Spin-valve effect and magnetoresistivity in single crystalline Ca3Ru2O7
Wei Bao, Z. Q. Mao, Z. Qu +1
The laminar perovskite Ca3Ru2O7 naturally forms ferromagnetic double-layers of alternating moment directions, as in the spin-valve superlattices. The mechanism of huge magnetoresis…
Anomalous critical behavior near the quantum critical point of a hole-doped La2CuO4
Y. Chen, Wei Bao, J. E. Lorenzo +4
The Landau-Ginzburg-Wilson paradigm for critical phenomena is spectacularly successful whenever the critical temperature is finite and all fluctuation modes, with characteristic en…
Crystal Field Effects in CeIrIn5
A. D. Christianson, J. M. Lawrence, P. S. Riseborough +9
In this work, we study crystalline electric field effects in the heavy fermion superconductor CeIrIn5. We observe two regions of broad magnetic response in the inelastic neutron sc…
Crystalline Electric Field Excitations in the Heavy Fermion Superconductor CeCoIn_5
E. D. Bauer, A. D. Christianson, J. M. Lawrence +9
The crystalline electric field (CEF) energy level scheme of the heavy fermion superconductor CeCoIn_5 has been determined by means of inelastic neutron scattering (INS). Peaks obse…
