Mutual phase-locking of microwave spin torque nano-oscillators

Article Abstract:

Two single spin torque nano-oscillators (STNOs) in close proximity mutually phase-lock that is they synchronize, which is a general tendency of interacting nonlinear oscillator systems. The phase-locked state is distinct, characterized by a sudden narrowing of signal linewidth and an increase in power due to the coherence of the individual oscillators.

Silver nanoswitch

Article Abstract:

A considerable amount of research is going on to find a reliable switching mechanism that can beat conventional silicon technology to permit ever smaller and more powerful electronics. The ideal switch would be one which is about the size of an atom, consumes the least power and utilizes only two leads for both reading and writing memory operations.

Quantized conductance atomic switch

Article Abstract:

A novel form of nanodevice called quantized conductance atomic switch (QCAS) which has low fabrication expense and requires less energy is discussed. This device functions by checking the development and annihilation of the atomic bridge at the junction of intersection among the two electrodes.
