2014 From magnetoresistance measurements in PtFe and PdCo alloys we show that disalignment within the ferromagnetic state begins at concentrations well above a critical concentration at which spin glass order sets in. In PtFe the ferromagnetic to spin glass transition is second order. J. Physique LETTRES 42 (1981) L-17 L-20 ler JANVIER 1981, 9 Classification Physics Abstracts 72.15G 75.30K 2.15...

A theoretical model for laser cooled continuous-wave fiber amplifier is presented. The amplification process takes place in the Tm 3+ -doped core of the fluoride ZBLAN (ZrF4-BaF2LaF3-AlF3-NaF) glass fiber. The cooling process takes place in the Yb 3+ :ZBLAN fiber cladding. It is shown that for each value of the pump power and the amplified signal there is a distribution of the concentration of ...

The output power performance of 0.50 um dual recessed pHEMT MMICs designed with current limited load lines strongly depends on the RF current swing of the device. What might seem a sufficient DC Imax of a given sample might not necessarily indicate the intrinsic output power capability of the device. The position and electrochemistry of the wide recess surface were demonstrated as important fac...

The demand for ever higher data rates is driving research for broadband wireless communications to data rates of 100 Gbit/s and beyond. This workshop presents research work on 100 Gbit/s wireless communications that uses carrier frequencies beyond 200 GHz with bandwidths of 20 GHz or more and moderate spectral efficiencies. Various wireless system and component design aspects are covered includ...

The force between two inert, planar surfaces in a liquid is discussed, focusing on the e ect of the reduction in the uid density between the surfaces. We use a density functional treatment of the uid, the results of which are veri ed by comparison with Grand Canonical Monte Carlo simulations. Our calculations reveal the existence of an attractive force between the surfaces, which at short and i...

Advanced Receiver Autonomous Integrity Monitoring extends RAIM to multiple constellations and dual frequency, with the goal of providing worldwide coverage of vertical guidance for aircraft. Availability simulations have shown that ARAIM based on GPS L1-L5 and Galileo E1-E1a could provide global coverage of vertical guidance. However these simulations rely on a set of assumptions on the measure...

1. An understanding of the vertical movements elasmobranchs across their range is crucial to defining critical habitat use, its overlap with anthropogenic activities and subsequently managing such interactions. 2. In this study, satellite telemetry was used investigate use three oceanic manta rays (Mobula birostris) tagged on northern coast Peru. 3. All mantas exhibited patterns reverse diel mi...
