Spin-lattice order in frustrated ZnCr2O4
S. Ji, S. -H. Lee, C. Broholm +4
Using synchrotron X-rays and neutron diffraction we disentangle spin-lattice order in highly frustrated ZnCrO where magnetic chromium ions occupy the vertices of regular te…
Spin phonon coupling in frustrated magnet CdCrO
R. Valdés Aguilar, A. B. Sushkov, Y. J. Choi +2
The infrared phonon spectrum of the spinel CdCr2O4 is measured as a function temperature from 6 K to 300K. The triply degenerate Cr phonons soften in the paramagnetic phase as temp…
Neel to Spin-Glass-like Phase Transition versus Dilution in Geometrically Frustrated ZnCr_{2-2x}Ga_{2x}O_4
S. -H. Lee, W. Ratcliff, Q. Huang +2
ZnCr2O4 undergoes a first order spin-Peierls-like phase transition at 12.5 K from a cubic spin liquid phase to a tetragonal Neel state. Using powder diffraction and single crystal…
Probing spin correlations with phonons in the strongly frustrated magnet ZnCr2O4
A. B. Sushkov, H. D. Drew, O. Tchernyshyov +2
The spin-lattice coupling plays an important role in strongly frustrated magnets. In ZnCrO, an excellent realization of the Heisenberg antiferromagnet on the ``pyrochlore''…
First-order nature of the ferromagnetic phase transition in (La-Ca)MnO_3 near optimal doping
C. P. Adams, J. W. Lynn, V. N. Smolyaninova +6
Neutron scattering has been used to study the nature of the ferromagnetic transition in single crystals of La_0.7Ca_0.3MnO_3 and La_0.8Ca_0.2MnO_3, and polycrystalline samples of L…
