Spin-lattice order in frustrated ZnCr2O4 (2009)
Ji, S., Broholm, C., Koo, T. Y., Ratcliff, W., Cheong, S-W., ...
Using synchrotron X-rays and neutron diffraction we disentangle spin-lattice order in highly frustrated ZnCr$_2$O$_4$ where magnetic chromium ions occupy the vertices of regular tetrahedra. Upon...
Origin of electromagnon excitations in \textit{R}MnO$_3$ (2008)
Aguilar, R. Valdés, Mostovoy, M., Sushkov, A. B., Zhang, C. L., Choi, Y. J., Cheong, S-W., ...
The origin of electromagnon excitations in cycloidal \textit{R}MnO$_3$ is explained in terms of the Heisenberg coupling between spins despite the fact that the static polarization arises from the...
