  Large amplitude spin-Hall oscillations are identified in a ferromagnetic
layer with two perpendicular in-plane easy axis in the presence of field-like
torque without any polarizer and external field. The analytical study confirms
the possibility of oscillations in the presence of field-like torque. The
investigation shows that the oscillation frequency can be tuned from 2 GHz to
80 GHz by current and enhanced by field-like torque. Further, the enhancement
of frequency along with the Q-factor by current and field-like torque is also
observed.
