Query: Spin-Torque Diode Measurements of MgO-Based Magnetic Tunnel Junctions
  with Asymmetric Electrodes   We present a detailed study of the spin-torque diode effect in
CoFeB/MgO/CoFe/NiFe magnetic tunnel junctions. From the evolution of the
resonance frequency with magnetic field at different angles, we clearly
identify the free-layer mode and find an excellent agreement with simulations
by taking into account several terms for magnetic anisotropy. Moreover, we
demonstrate the large contribution of the out-of-plane torque in our junctions
with asymmetric electrodes compared to the in-plane torque. Consequently, we
provide a way to enhance the sensitivity of these devices for the detection of
microwave frequency.
