Magnetic excitations in La1.5Sr0.5CoO4
Physica B Elsevier 350 (2004) e273-e275
Abstract:
We report magnetization and neutron scattering measurements of the half-doped compound La1.5Sr0.5CoO4, which exhibits a checkerboard pattern of charge ordering below not, vert, similar800 K. In the antiferromagnetically-ordered phase below not, vert, similar40 K 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.Phonon dispersion relations in PrBa2Cu3O6+x (x≈0.2) -: art. no. 092302
