On the basis ofSchöler's theory of boundary conditions for the pair potential in clean superconductors, corrections are obtained to standard results forH c∥. They are given explicitely both for thin and thick films. The results should be valid forT in the neighbourhood ofT c . The thin film corrections do not vanish even in the limitT→T c . 相似文献

A numerical mistake made in a previous paper is corrected. For specular reflexion of electrons by the surface the result now agrees with a result obtained earlier byEbneth andTewordt. In order to facilitate a comparison with experimental data the calculation of the ratioH c3(T)Hc2(T) is extended up to terms linear (T c ?T)/T c for arbitrary reflexion kernels. 相似文献

We present the results of an experiment performed at PSI to investigate muon catalyzed fusion in pure deuterium gas of 5%
density (LHD) at temperatures ranging from 28 K to 350 K. Using a new high pressure ionization chamber the reactions dd → n + 3He and dd → p+t were observed with 100% detection efficiency. The rates of dμd formation were measured with the absolute precision of 1% and the μd spin-flip rates with 0.5%. The temperature dependence of molecular formation and spin-flip rates display pronounced resonance
structures. A preliminary fit based on the Vesman mechanism of resonant muonic molecule formation was carried out yielding
a dd fusion rate of 3.5·108 s-1 and a hfs splitting energy
of 24.3 meV, both in good agreement with the theory.

Magnetization of ferromagnetic materials commonly occurs via random jumps of domain walls between pinning sites, a phenomenon known as the Barkhausen effect. Using strongly focused light pulses of appropriate power and duration we demonstrate the ability to selectively activate single jumps in the domain wall propagation in (Ga,Mn)As, manifesting itself as a discrete photoinduced domain wall creep as a function of illumination time. The propagation velocity can be increased over 7 orders of magnitude varying the illumination power density and the magnetic field. 相似文献

A theoretical study has been carried out on two methoxyphenyl derivatives (tetrakis‐(p‐methoxyphenyl)‐ porphyrin and the Zn‐containing complex), which are the reduced size representation of the alkyl peripheral substituent systems. The aim is to study the electronic interactions on these aromatic cores which is one of the most important properties in discotic liquid crystals. Their face‐to‐face dimeric conformation systems were studied in order to evaluate charge transport properties, by assessing the intermolecular charge transfer integrals “t” in the context of the Marcus electron transfer theory. The intermolecular transfer integral has been calculated from the matrix elements of the Kohn–Sham Hamiltonian including dispersion correction for noncovalent interacting systems. The results indicate that the effect of the Zn center in these porphyrins is nearly negligible and both studied systems can act as electron carriers, which are also seen in the bonding interaction of the LUMO orbitals. © 2013 Wiley Periodicals, Inc. 相似文献
