Origin of the spectral linewidth in non linear oscillators based on MgO tunnel junctions

, 2009
We demonstrate the strong impact of the oscillator agility on the line broadening by studying spin transfer induced microwave emission in MgO-based tunnel junctions with current. The linewidth is almost not affected by decreasing the temperature. At very
