“…White's design principles were adopted and improved by a number of researchers [Refs. [14][15][16][17][18][19]. Capacitance dilatometers based on parallel spring movement are well established and have been described for instance by Pott and Schefzyk [Ref.…”

We describe the design, construction, calibration, and two different applications of a miniature capacitance dilatometer. The device is suitable for thermal expansion and magnetostriction measurements from 300 K down to about 25 mK, with a resolution of 0.02 Å at low temperatures. The main body of the dilatometer is fabricated from a single block of a Be-Cu alloy by electrical discharge milling. This creates an extremely compact high-resolution measuring cell. We have successfully tested and operated dilatometers of this new type with the commonly used physical property measurement system by quantum design, as well as with several other cryogenic refrigeration systems down to 25 mK and in magnetic fields up to 20 T. Here, the capacitance is measured with a commercially available capacitance bridge. Using a piezoelectric rotator from Attocube Systems, the cell can be rotated at T = 25 mK inside of an inner vacuum chamber of 40 mm diameter. The miniaturized design for the one-axis rotation setup allows a rotation of 360°.

“…The thermal expansion measurements were performed using a capacitance dilatometer similar to that descr!bed by Brandli and Griessen [4] but with several modifications and improvements 15]. The change in the sample's length, AL, was measured at 5 K intervals and the linear expansion coefficient, ~ = (1/L)dL/dT, was determined by differentiating a cubic spline interpoLdon.…”

“…Yet this rate is not sufficient to put our InPb nanowires into the insulating regime. The observed superconducting transition has a width of about 0.5 K, and its center occurred at T = 5.0 K, i.e., at temperatures close to T c for a bulk alloy of this composition [23]. When heated above a transition the measured resistance is mainly determined by the resistance of nanowires themselves, and it weakly decreases with temperature according to dependence…”

a b s t r a c tNanowires of niobium, platinum and indium-lead In 88 Pb 12 alloy with diameters of 4.2, 3.6 and 8 nm, respectively, were grown in quantized vortices of superfluid helium, and the dependences of their resistance on temperature have been studied. Through a detailed comparison of these dependences we present evidence that superconducting niobium wires allow a high rate of quantum phase slip. This phase slippage leads to a phase transition to an insulating state at T ? 0.
