“…The lattice constant of the Co(1.5 nm)/Pd(2.6 nm) multilayer, which is obtained from the fcc(111) peak position, is shown in figure 3 as a function of the thickness fraction of the Pd layer. A previously reported [12] lattice constant of the Co(1.6 nm)/Pd(4.0 nm) multilayer fabricated by sputtering is also shown in figure 3. In figure 3 ) solid solutions.…”

We compare two Co/Pd multilayers with correspondingly smooth and rough interfaces. The first is a Co (1.5 nm)/Pd (2.6 nm) multilayer with a smooth interface deposited by the MBE technique, and the second is a Co (1.6 nm)/Pd (4.0 nm) multilayer with a rough interface deposited by the sputter technique. Both multilayers have almost the same perpendicular magnetic anisotropy energy, 1.15 Merg/cc for the Co (1.5 nm)/Pd (2.6 nm) multilayer and 1.20 Merg/cc for the Co (1.6 nm)/Pd (4.0 nm) multilayer, respectively. The symmetry of the wave function, which is measured using the magnetic Compton profile, is almost the same for both multilayers. This suggests that the smooth interface controls the wave function and enhances the PMA energy even if the Co/Pd multilayer has a thinner Pd layer.

“…More details on the processing and properties of these composites can be found elsewhere. 21,22 As noted above, the Ti 3 SiC 2 samples were subjected to tensile stresses in the 1000-1200°C temperature range. 10,11 The samples were placed in a box furnace, attached to SiC pull-rods using a pin and clevis arrangement, heated to the testing temperature in ϳ1.5 h and presoaked for 2 to 4 h prior to applying the load in order to insure equilibrium.…”

We report herein on the oxidation kinetics and morphology of the oxide phases that form after long term ͑up to 1500 h͒ oxidation in ambient air of fine and coarse-grained samples of Ti 3 SiC 2 , Ti 3 SiC 2 , with 30 vol % TiC and Ti 3 SiC with 30 vol % SiC in the 875-1200°C temperature range. In all cases, the oxidation resulted in a duplex scale, an outer rutile and an inner rutile/silica layer. At 875°C, and up to at least 100 h, the oxidation kinetics of the Ti 3 SiC 2 /30 vol % TiC samples are parabolic; at 925°C, the oxidation kinetics of the Ti 3 SiC 2 /30 vol % SiC are subparabolic, up to at least 500 h. The oxidation kinetics of all other runs are initially parabolic, but at times Ͼ30 h they become linear. The reason for the transition is not entirely clear, but could be due to the buildup of stresses in the external oxide scales. Comparison with previously published results indicate that the rate limiting step, when the oxidation kinetics are parabolic, is most probably the inward diffusion of oxygen and the simultaneous outward diffusion of titanium. The results also strongly suggest that the activation energies for diffusion of oxygen and titanium in rutile are almost identical over at least the 1000-1200°C temperature range.

“…The repetition rate of the probe laser is offset locked by 100 Hz from that of the pump, sweeping the probe pulse train through 12.5 ns of delay time (the round-trip time of the oscillator cavities) over 10 ms in the lab frame. A second lock circuit stabilizes the repetition rate of the pump laser over time scales ≥1 s. The full details of the lock circuits and THz optics are reported elsewhere [19,20]. The polarization of the probe light is measured by a balanced detector, and digitized.…”

Decade-Spanning High-Precision Terahertz Frequency Comb

et al. 2015

View full text Add to dashboard Cite

The generation and detection of a decade-spanning terahertz (THz) frequency comb is reported using two Ti:sapphire femtosecond laser oscillators and asynchronous optical sampling THz time-domain spectroscopy. The comb extends from 0.15 to 2.4 THz, with a tooth spacing of 80 MHz, a linewidth of 3.7 kHz, and a fractional precision of 1.8 × 10 −9 . With time-domain detection of the comb, we measure three transitions of water vapor at 10 mTorr between 1-2 THz with an average Doppler-limited fractional accuracy of 6.1 × 10 −8 . Significant improvements in bandwidth, resolution, and sensitivity are possible with existing technologies.
