We study the current and temperature dependences of the microwave voltage
emission of spin-valve nanopillars subjected to an in-plane magnetic field and
a perpendicular-to-plane current. Despite the complex multilayer geometry,
clear microwave emission is shown to be possible and spectral lines as narrow
as 3.8 MHz (at 150 K) are observed.
