Dynamic magnetoelectric effect in ferromagnet/superconductor tunnel junctions.
We study the magnetization dynamics in a ferromagnet/insulator/superconductor tunnel junction and the associated buildup of the electrical polarization. We show that for an open circuit, the induced voltage varies strongly and nonmonotonically with the precessional frequency, and can be enhanced significantly by the superconducting correlations. For frequencies much smaller or much larger than ...
متن کاملJosephson effect in small - area superconducting tunnel junctions at 604
We have measured the ac Josephson effect in small-area superconducting tunnel junctions at 604 GHz (A = 496pm) using a resonant planar dipole antenna to couple the radiation into the junction. In a 176-fl junction, we have observed up to the 7th Josephson step (at 8.75 m V), a performance comparable to that seen in point contacts. We also compare our data with the results of the RSJ model and o...
متن کاملSpin Josephson effect in ferromagnet/ferromagnet tunnel junctions
– We consider the tunnel current between two ferromagnetic metals from a perspective similar to the one used in superconductor/superconductor tunnel junctions. We use fundamental arguments to derive a Josephson-like tunnel spin current I J ∝ sin(θ1 − θ2). Here the phases are associated with the planar contribution to the magnetization, 〈c†↑c↓〉 ∼ e . The crucial step in our analysis is the fact ...
متن کاملMagnetic Tunnel Junctions
Application of Bardeen’s tunneling theory to magnetic tunnel junctions having a general degree of atomic disorder reveals the close relationship between magneto-conduction and voltage-driven pseudo-torque, as well as the thickness dependence of tunnel-polarization factors. Among the results: 1) The torque generally varies as sin θ at constant applied voltage. 2) Whenever polarization factors ar...

Figure 1 Schematic illustration showing the mechanism of TMR. Top: for parallel aligned magnetization as sketched at left, electrons around the Fermi level with spin up (m) and spin down (k) are allowed to tunnel from majority to majority bands, and from minority to minority bands. Bottom: when the magnetization is antiparallel, tunneling takes place from majority to minority and minority to ma...
