Abstract

The spin and lattice excitations in the CMR ferromagnet La_0.70Ca_0.30MnO₃ (LCMO30) have been studied by the use of polarized inelastic neutron scattering. This work has been carried out on a large single crystal using the IN20 polarized triple axis spectrometer at the Institut Laue Langevin, Grenoble, France. The spin waves and the lowest lying optical phonons both show a considerable degree of broadening and the use of polarized neutrons has been essential in order to separate these two components of the scattering.
