Magnetic excitations in LaSrCoO
arXiv:cond-mat/0310778 · doi:10.1016/j.physb.2004.03.068
Abstract
We report magnetization and neutron scattering measurements of the half-doped compound LaSrCoO, which exhibits a checkerboard pattern of charge ordering below ~800K. In the antiferromagnetically-ordered phase below \~40K the spins are found to be canted in the ab plane. The spin excitation spectrum includes spin-wave excitations with a maximum energy of 16 meV, and diffuse magnetic modes at energies around 30 meV.
