Title: Effect of magnetic field on quasiparticle branches of intrinsic Josephson junctions with ferromagnetic layer.

Abstract

The interlayer tunneling spectroscopy has been performed on micron-sized mesa arrays of HgBr{sub 2} intercalated superconducting Bi2212 single crystals. A ferromagnetic multilayer (Au/Co/Au) is deposited on top of the mesas. The spin-polarized current is driven along the c-axis of the mesas through a ferromagnetic Co layer and the hysteretic quasiparticle branches are observed at 4.2 K. Magnetic field evolution of hysteretic quasiparticle branches is obtained to examine the effect of injected spin-polarized current on intrinsic Josephson junction characteristics. It is observed that there is a gradual distribution in quasiparticle branches with the application of magnetic field and increasing field reduces the switching current progressively.

  • The size effect in circularly symmetric, annular Josephson junctions is discussed in detail. For a junction of width {ital W}, we find that there exists a minimum inner radius {rho}{sub min} for resonant soliton motion within the junction, with respect to the dissipative parameter and external magnetic field, and that the applied magnetic field plays an important role in reducing the size effect ({rho}{sub min} decreases remarkably in the presence of a negative external magnetic field). Because of the size effect, the range of the first current step vanishes if the inner radius of the annular junction is smaller thanmore » {rho}{sub min}. A qualitative interpretation is given for the size effect. On the basis of our results, future physical experiments are suggested.« less
  • The presence of zero field steps (ZFS) on the voltampere characteristics of long Josephson junctions has been generally accepted as a manifestation of fluxon propagation. Each step represents an equal number of fluxons and antifluxons resonating in the junction in a period fixed by the junction length. However, extra steps have been experimentally observed which appear to correspond to non-integral numbers of fluxons traversing the junction in one period. The authors use a computer simulation of the sine-Gordon equation and a separate mechanical model to demonstrate that it is feasible to maintain a different number of fluxons and antifluxons inmore » the junction within one period. With the appropriate choice of asymmetric boundary conditions corresponding to an applied magnetic field, one end of the junction, upon arrival of an antifluxon, may release one or more extra fluxons, while the opposite end is capable of absorbing these extra fluxons. Thus, the number of fluxons passing through a given point in the junction is not equal to the number of antifluxons passing the same point within a period. If the difference between the number of fluxons and antifluxons is an odd number, steps in addition to ZFS appear on the volt-ampere characteristic. The authors demonstrate that a variety of complex step behavior in magnetic fields can be explained by using the concept of creation and annihilation of fluxons at the boundaries.« less
  • We study ultrasmall Josephson junctions using the coherent picture to describe the pair dynamics and the semiclassical approach for the quasiparticles. We find that the dynamics depends crucially on the ratio of the superconducting gap energy ..delta..(T) to the charging energy e/sup 2/2C. The pair ''Bloch oscillations'' can be practically observed when 2..delta..(T)>e/sup 2/2C;for 2..delta..(T)
  • Experiments have been carried out on the effect of a nonequilibrium flow of quasiparticles on the Josephson properties of a Ta-Cu-Ta SNS junction. A nonequilibrium quasiparticle flow can be set up at the junction because the thickness of the superconducting banks of the SNS sandwich is on the order of the depth to which the longitudinal electric field penetrates into the superconductor, and the sandwich is bracketed by thick plates of a normal metal. During the injection of quasiparticles into one of the superconducting banks of the SNS junction, Josephson generation is excited at the junction; the total current flowingmore » across the junction is zero. The nonequilibrium quasiparticle current which flows across the SNS junction is several times the critical current I/sub c/ and has no direct effect on its Josephson characteristics. The appearance of a difference in the electrochemical potentials of the pairs and of Josephson generation at the junction is due exclusively to the flow of the superconducting current. The experimental results are analyzed on the basis of an equivalent circuit proposed for the junction by Kadin, Smith, and Skocpol (J. Low Temp. Phys. 38, 497 (1980)), simplified somewhat for the case at hand. A study of the temperature dependence of the effects shows that at T> or =0.97T/sub c/ the nonequilibrium quasiparticle current in the normal Josephson intermediate layer of the junction does not depend on Andreev reflection processes at the NS interfaces. The scale time for electron-phonon energy relaxation in the tantalum used as the superconductor is estimated to be tau/sub Epsilon/roughly-equal 4.0 x 10/sup -1/ s.« less
  • Deposition of ZnO thin films on a ferromagnetic metallic buffer layer (Co{sub 3}Pt) by molecular beam epitaxy technique was investigated for realization of ZnO-based magnetic tunneling junctions with good quality hexagonal ZnO films as tunnel barriers. For substrate temperature of 600 Degree-Sign C, ZnO films exhibited low oxygen defects and high electrical resistivity of 130 {Omega} cm. This value exceeded that of hexagonal ZnO films grown by sputtering technique, which are used as tunnel barriers in ZnO-MTJs. Also, the effect of oxygen flow during deposition on epitaxial growth conditions and Co{sub 3}Pt surface oxidation was discussed.
