Using a membrane-driven diamond anvil cell and both ac magnetic susceptibility and electrical resistivity measurements, we have characterized the superconducting phase diagram of elemental barium to pressures as high as 65 GPa. We have determined the superconducting properties of the recently discovered Ba-VI crystal structure, which can only be accessed via the application of pressure at low temperature. We find that Ba-VI exhibits a maximum Tc near 8 K, which is substantially higher than the maximum Tc found when pressure is applied at room temperature.

We report the first measurements of the anisotropic upper critical field $H_{c2}(T)$ for K$_{2}$Cr$_{3}$As$_{3}$ single crystals up to 60 T and $T > 0.6$ K. Our results show that the upper critical field parallel to the Cr chains, $H_{c2}^parallel (T )$, exhibits a paramagnetically-limited behavior, whereas the shape of the $H_{c2}^perp (T)$ curve (perpendicular to the Cr chains) has no evidence of paramagnetic effects. As a result, the curves $H_{c2}^perp (T)$ and $H_{c2}^parallel(T)$ cross at $Tapprox 4$ K, so that the anisotropy parameter $gamma_H(T)=H_{c2}^perp/H_{c2}^parallel (T)$ increases from $gamma_H(T_c)approx 0.35$ near $T_c$ to $gamma_H(0)approx 1.7$ at 0.6 K. This behavior of $H_{c2}^|(T)$ is inconsistent with triplet superconductivity but suggests a form of singlet superconductivity with the electron spins locked onto the direction of Cr chains.
When investigating low-frequency (0.1 Hz) oscillations of miltiphase high-temperature cuprate superconductors (HTSC) Bi1,7Pb0,3Sr2Ca(n-1)CunOy (n=2-30), a wide attenuation peak with a maximal at T=200K detected. This peak was particularly pronounced in field cooling (FC) experiments, i.e. after abrupt cooling of the sample in the external magnetic field at the temperature T less Tc with subsequent slow warming up to room temperature with invariance of applied field. The attenuation peak height depended on the preliminary orientation (before cooling) of the samples in the measured permanent magnetic field H. On the one hand, it is well khow that, after the FC procedure and subsequent slow warming up, at the temperatures close to the critical temperature Tc, the attenuation peak associated with melting of the Abrikosov frozen vortex structure and its disappearance at T more Tc is detected in monophase samples. At the same time, in most multiphase bismuth HTSC samples, synthesized using solar energy and superfast quenching of the melt, the attenuation peak with the maximum at T=200K was observed. Depending on the conditions of synthesis, the attenuation peak could be two-humped and could be located in the temperature range much wider than Tc of the major superconducting phase. We assume that this is due to the existence of frozen magnetic fluxes (after FC) in superconducting dropping regions, which gradually (with increasing temperature) transfer into the normal state and release pinned vortex threads. This fact could be a sause of observed dissipative processes, so as also the evidence of the existence of superconductivity at T more 240K.
A commercially available calorimeter has been used to investigate the specific heat of a high-quality kn single crystal. The addenda heat capacity of the calorimeter is determined in the temperature range $0.02 , mathrm{K} leq T leq 0.54 , mathrm{K}$ . The data of the kn crystal imply the presence of a large $T^2$ contribution to the specific heat which gives evidence of $d$-wave order parameter symmetry in the superconducting state. To improve the measurements, a novel design for a calorimeter with a paramagnetic temperature sensor is presented. It promises a temperature resolution of $Delta T approx 0.1 , mathrm{mu K}$ and an addenda heat capacity less than $200 , mathrm{pJ/K}$ at $ T < 100 , mathrm{mK}$.
We describe an alternating current method to measure the Nernst effect in superconducting thin films at low temperatures. The Nernst effect is an important tool in the understanding superconducting fluctuations and, in particular, vortex motion near critical points. However, in most materials, the Nernst signal in a typical experimental setup rarely exceeds a few $mu$V, in some cases being as low as a few nV. DC measurements of such small signals require extensive signal processing and protection against stray pickups and offsets, limiting the sensitivity of such measurements to $>$5nV. Here we describe a method utilizing a one-heater-two-thermometer setup with the heating element and thermometers fabricated on-chip with the sample, which helped to reduce thermal load and temperature lag between the substrate and thermometer. Using AC heating power and 2$omega$ measurement, we are able to achieve sub-nanovolt sensitivity in 20-30nm MoGe thin films on glass substrate, compared to a sensitivity of $sim$9nV using DC techniques on the same setup.
Formation of MgB2 by reactions of Mg with B6Si and Mg with B were compared, the former also producing Mg2Si as a major product. Compared to the binary system, the ternary reactions for identical time and temperature were more complete at 750 C and be low, as indicated by higher diamagnetic shielding and larger x-ray diffraction peak intensities relative to those of Mg. MgB2 could be produced at temperatures as low as 450 C by the ternary reaction. Analyses by electron microscopy, x-ray diffraction, and of the upper critical field show that Si does not enter the MgB2 phase.
