“…One reason for the relatively high R B values is the likelihood that some RE 2 CoGa 8 may be present as a minor impurity phase, as suggested by slight broadening of the peaks. All peaks in the powder diffraction pattern of RE 2 16 were difficult to prepare in high purity. As ascertained by powder X-ray diffraction, four samples (RE = Gd, Tb, Dy, Y) could be obtained in adequate purity (less than ca.…”

Keywords: Rare earths / Cobalt / Gallium / Intermetallic phases / Magnetic properties Ternary rare-earth cobalt gallides RE 4 Co 3 Ga 16 (RE = Gd-Er, Y) have been prepared by arc-melting of the elements followed by annealing at 800°C. Single crystals of the Gd and Tb members were also grown in the presence of a Ga selfflux. They extend the rare-earth substitution possible in the Sm 4 Co 3 Ga 16 -type structure (Pearson symbol tP23, space group P4/mmm, Z = 1), in which additional Co atoms enter as self-interstitials into the parent RE 2 CoGa 8 structure. Structural refinements were carried out on single-crystal (RE = Gd, Tb) and powder (RE = Dy, Ho, Er, Y) X-ray diffraction data. Cell parameters lie in the ranges of a = 6.03-5.96 Å and c =

“…15 It must be pointed out that complete screening needs much longer time and relaxation processes can be revealed even in hours and days after polarization reversal. 24 The domain wall starts to move from the initial position if the switching pulse amplitude is above the threshold value. The wall motion velocity v gradually decreases with shift from the initial position, due to increase of E rd produced by the trail.…”

The polarization reversal and domain structure evolution has been studied in stoichiometric lithium tantalate prepared by vapor transport equilibration process. The first in situ visualization of domain kinetics has demonstrated the jump-like motion of few strictly oriented plane domain walls, which leads to short isolated current pulses in the switching current data. The proposed model of jump-like domain wall motion caused by interaction with pinning centers representing the areas with increased value of the threshold field is based on the effect of retardation of bulk screening. The derived formulas were applied successfully for analysis of the field dependence of the total switching time. The durations of wall jumps and wall stays (rest times) extracted from the switching current data are analyzed separately. The deceleration of the wall motion velocity during jump is controlled by the trail of residual depolarization field produced by bound charges and screening charges in the area behind the wall. The duration of the rest time is governed by the bulk screening of residual depolarization field. The value of Hurst exponent 0.75 obtained by fractal analysis of the switching current data has confirmed the essential influence of prehistory on the domain wall motion. The measurements of the coercive field by switching in bipolar triangular pulses in wide range of the field ramp rate have allowed us to extract the record low value of coercive field 60 V/mm for quasi-static polarization reversal.

We demonstrate using a simple model that in the frame of muffin-tin -like potential nonphysical peculiarities appear in molecular photoionization cross-sections that are a consequence of "jumps" in the potential and its first derivative at some radius. The magnitude of non-physical effects is of the same order as the physical oscillations in the cross-section of a two-atomic molecule. The role of the size of these "jumps" is illustrated by choosing three values of it.The results obtained are connected to the studied previously effect of non-analytical behavior as a function of r of the potential ( ) Vr acting upon a particle on its photoionization crosssection. In reality, such potential has to be analytic in magnitude and first derivative function in r . Introduction of non-analytic features in model ( ) V r leads to non-physical features in the corresponding cross-section -oscillations, additional maxima etc.
