Abstract
We study the growth, stacking and superconducting properties of Nb and B thin films and superlattices. The interest in these resides in their possible use in transition edge neutron sensors. The samples were grown by magnetron sputtering over Si (100) substrates. The X-ray diffraction patterns for all Nb containing samples show a Nb (110) preferential orientation. From the low-angle X-ray reflectivity we obtain information on the superlattice structure. The superconducting transition temperatures of the superlattices, obtained from the temperature dependence of the magnetization, are higher than those of single Nb films of similar thickness. The temperature dependence of the perpendicular and parallel upper critical fields indicate that the superlattices behave as an array of decoupled superconducting Nb layers. |

Abstract |
This paper presents two capacitive comb drive
designs for electrostatic actuation of MEMS with the aim to
eliminate the levitation effect often observed in such systems.
By placing a shield over the comb drive fingers, it is possible
to balance the electric field and suppress vertical forces while
maintaining the desired lateral motion. By optimizing the comb
geometry, we demonstrate that our approach is able to reduce the
levitation by an order of magnitude and unwanted coupling of
motion from out-of-plane to in-plane by a factor of 7 compared
with standard comb architectures fabricated using PolyMUMPs
technology, without the need of alternating comb finger polarities
or additional control electrodes. Levitation was reduced to
160 nm, for 3.6-µm lateral displacement at a driving voltage
of 80 V. |

Abstract |
Low temperature thermal and magnetic measurements performed on ferro-magneticl (FM) alloys of composition Ce2.15(Pd1−x Ag x )1.95In0.9 are presented. Pd substitution by Ag depresses ${{T}{\text{C}}}(x)$ from 4.1 K down to 1.1 K for x  =  0.5, which is related to the increase of band electrons, with a critical concentration extrapolated to ${{x}{\text{cr}}}\approx 0.6$ . The ${{T}{\text{C}}}(x)$ decrease is accompanied by a weakening of the magnetization of the FM phase. At high temperature (T  >  30 K) the inverse magnetic susceptibility reveals the presence of robust magnetic moments ($2.56\geqslant ~{{\mu}{\text{eff}}}\geqslant 2.4$ ${{\mu}{\text{B}}}$ ), whereas the low value of the Curie–Weiss temperature ${{\theta}{P}}\approx -10$ K excludes any relevant effect from Kondo screening. The specific heat jump at ${{T}{\text{C}}}(x)$ decreases accordingly, while an anomaly emerges at a fixed temperature ${{T}^{\ast}}\approx 1$ K. This unexpected anomaly does not show any associated sign of magnetism checked by AC-susceptibility measurements. Since the total magnetic entropy (evaluated around $T={{T}{\text{C}}}(x=0)$ ) practically does not change with Ag concentration, the transference of degrees of freedom from the FM component to the non-magnetic T * anomaly is deduced. The origin of this anomaly is attributed to an arising magnetic frustration of the ground state and the consequent entropy bottleneck produced by the divergent increasing of density of excitations at low temperature. |
