Evolution of the low-frequency spin dynamics in ferromagnetic manganites

J. A. Fernandez-Baca, P. Dai, H. Y. Hwang +2

Elastic and inelastic neutron scattering was used to study two ferromagnetic manganites A${}_{1-x}$B${}_x$MnO${}_3$ (x $\approx$ 0.3) with $T_c$=197.9 K and 300.9 K. The spin dynamical…
