High resolution x-ray study of nematic-smectic-A and Smectic-A-reentrant nematic transitions in liquid crystal+aerosil gels
M. Ramazanoglu, S. Larochelle, C. W. Garland +1
We have studied the effects of quenched random disorder created by dispersed aerosil nanoparticle gels on the nematic to smectic-A (N-SmA) and smectic-A to reentrant nematic (SmA-…
Quasi-stationary criticality of the Order-Parameter of the d=3 Random-Field Ising Antiferromagnet Fe(0.85)Zn(0.15)F2: A Synchrotron X-ray Scattering Study
F. Ye, L. Zhou, S. A. Meyer +5
The critical exponent beta =0.17(1) for the three-dimensional random-field Ising model (RFIM) order parameter upon zero-field cooling (ZFC) has been determined using extinction-fre…
Structural and magnetic properties of the single-layer manganese oxide La{1-x}Sr{1+x}MnO4
S. Larochelle, A. Mehta, L. Lu +6
Using x-ray and neutron scattering, we have studied the structural and magnetic properties of the single-layer manganite La{1-x}Sr{1+x}MnO4 (0 < x < 0.7). Single crystals were grow…
Phase Decomposition and Chemical Inhomogeneity in Nd2-xCexCuO4
P. K. Mang, S. Larochelle, A. Mehta +7
Extensive X-ray and neutron scattering experiments and additional transmission electron microscopy results reveal the partial decomposition of Nd2-xCexCuO4 (NCCO) in a low-oxygen-f…
Susceptibilities and Spin Gaps of Weakly-coupled Spin Ladders
S. Larochelle, M. Greven
We calculate the uniform and staggered susceptibilities of two-chain spin-1/2 Heisenberg ladders using Monte-Carlo simulations. We show that the gap extracted from the uniform susc…
Spurious magnetism in high-Tc superconductor
P. K. Mang, S. Larochelle, M. Greven
One challenge in condensed-matter physics is to unravel the interplay between magnetism and superconductivity in copper oxides with a high critical temperature (Tc). Kang et al. cl…
