The gap anisotropy in Bi 2 Sr 2 CaCu 2 O 8+δ is revisited in the framework of a d-wave scenario in view of the recent angle-resolved photoemission experiment. Based on a tight-binding fit to the normal state dispersion, a detail analysis on the effects of the inclusion of the next harmonic in the d-wave has been presented. Significant effect has been observed in the superconducting T c. The den...

We describe a straightforward approach to the characterization of individual thin-film NiFe ferromagnets, useful from cryogenic to room temperature. The technique is based upon the local Hall effect (LHE), in which strong fringe fields present near the edge of a ferromagnet induce a Hall voltage in a nanoscale semiconducting cross-junction. Hysteresis loops are obtained for individual nanomagne...

In recent years, FinFET transistors have received much interest thanks to the better immunity to short-cannel effects [1]. DC characteristics of FinFETs at high temperature were recently reported in [2]. RF characteristics of Bulk Si MOSFETs measured at low temperature (77K) have been presented in a few papers [3]-[4]. To the knowledge of the authors, the DC and RF characteristics, over a wide ...

We present energy spectrum calculations of 5E term of Fe++ ion taking into account crystal field, spin-orbit interaction, uniaxial stress, magnetic field and dynamic Jahn-Teller effect. Basing on the obtained energy spectra we calculate magnetic properties (specific heat and magnetization) of Fe-based Semimagnetic Semiconductors. We found that presence of the JahnTeller effect has very small in...

Via Monte Carlo studies of the frustrated XY or classical planar model we demonstrate the possibility of a finite (nonzero) temperature spin/gauge glass phase in two dimensions. Examples of both periodic and quasiperiodic two dimensional lattices, where a high temperature paramagnetic phase changes to a spin/gauge glass phase with the lowering of temperature, are presented. The existence of the...

A Fabry-Perot interferometer sensor based on a fiber-tip bubble-structure micro-cavity is proposed, fabricated, and demonstrated for transverse load sensing. The micro-cavity is fabricated by using arc discharge at the end of a multimode fiber which has been processed with chemical etching. A transverse load sensitivity of 3.64 nm/N and a relative low temperature sensitivity of about 2 pm/◦C ar...

Sumintary. A spring wheat (Triticumo aestivumin) and(I anl obligate winter wheat (Triticumt compactutm) variety were each grown for 5 weeks in controlled environments at 20 and 250. The threshold for flower induction in the winter wheat was 4 to 5 weeks at 20, whereas the spring wheat had no low temperature requirement for flowering. Changes in the levels of carbohydrate and nitrogen fractions ...

Presently, there is much interest in molecular (nano)magnets with unique superparamagnetic properties, which may be used for quantum computing and memory storage [1-4]. A remarkable feature of nanomagnets is that these macromolecules with large effective molecular spin (e.g., S = 10 for Mn12acetate) can keep their spin orientation upon the reversal of the external magnetic field [3,4]. Because ...

Xiong * School of Transportation Science and Engineering, Beihang University, Beijing 100191, China; [email protected] * Correspondence: [email protected] Abstract: This paper seeks to model the crack propagation in of AAs (aluminum-alloys) 2524-T3 and 705...

We study the thermodynamic properties of an ideal gas of fermions in a harmonic oscillator confining potential. The analogy between this problem and the de Haasvan Alphen effect is discussed and used to obtain analytical results for the chemical potential and specific heat in the case of both isotropic and anisotropic potentials. Step-like behaviour in the chemical potential, first noted in num...
