We present the effect of temperature on the switching characteristics of a bistable nonlinear nanomechanical beam. At megahertz-range frequencies, we find that it is possible to controllably change the state of the system between two stable mechanical states defined by the hysteresis brought on by nonlinear excitation. We find that the introduction of increased temperature results in a loss of switching fidelity, and that temperature acts as an effective source of external noise on the dynamics of the system.

    Magnetic 1/f noise is one of the major noise sources in state-of-the-art magnetic tunneling read heads for hard disk drive applications. The 1/f noise can be induced by thermally activated magnetic switching of antiferromagnetic (AFM) grains in the reader stack. This noise mechanism is studied...
