Abstract

Doping dependent spin waves were measured in a two dimensional bilayer manganite. The results showed strong dependence of the interplane magnetic exchange, demonstrating the preferential filling of a band with decreasing hole concentration. Large low-temperature spin wave damping, rising linearly with spin-wave energy and containg no special resonances were observed. The double exchange phenomena explained the low-temperature spin-wave dispersion in the ferromagnetic bilayers.
