Inelastic neutron-scattering measurements were performed on a single crystal of the layered colossal magnetoresistance (CMR) material La 1.2 Sr 1.8 Mn 2 O 7 (T C t 120 K). We found that the spin wave dispersion is almost perfectly two-dimensional with the in-plane spin stiffness constant D t 151 meV

We present electron spin resonance measurements on single crystals of La Sr Mn O . A well-resolved multiline 1.2 1.8 2 7 spectrum is observed. There is one paramagnetic resonance line for temperatures above the ordering temperatures. The other ลฝ . lines turn out to arise from a small -0.1% volume f
