Supercooling of the A phase of $^{3}$ He

Yefan Tian, Dmytro Lotnyk, Anna Eyal +9

Because of the extreme purity, lack of disorder, and complex order parameter, the first-order superfluid $^{3}$ He A-B transition is the leading model system for first order transitio…

Path-Dependent Supercooling of the $^{3}$ He Superfluid A-B transition

Dmytro Lotnyk, Anna Eyal, Nikolay Zhelev +7

We examine the discontinuous first-order superfluid $^{3}$ He A to B transition in the vicinity of the polycritical point (2.232 mK and 21.22 bar). We find path-dependent transitions:…

Thermal transport of helium-3 in a strongly confining channel

D. Lotnyk, A. Eyal, N. Zhelev +8

In a neutral system such as liquid helium-3, transport of mass, heat, and spin provide information analogous to electrical counterparts in metals, superconductors and topological m…

Suppression of the superconductivity in ultrathin amorphous Mo $_{78}$ Ge $_{22}$ thin films observed by STM

D. Lotnyk, O. Onufriienko, T. Samuely +5

In contact with a superconductor, a normal metal modifies its properties due to Andreev reflection. In the current work, the local density of states (LDOS) of superconductor - norm…

Evolution of the fishtail-effect in pure and Ag-doped MG-YBCO

D. A. Lotnyk, R. V. Vovk, M. A. Obolenskii +8

We report on magnetic measurements carried out in a textured YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ and YBa $_{2}$ (Cu $_{1 - x}$ Ag $_{x}$ ) $_{3}$ O $_{7 - δ}$ (at $x \approx$ 0.02) crystals. The so-called fishtai…

Influence of aging on fishtail-effect in pure and Ag-doped MG-YBCO

D. Lotnyk, R. V. Vovk, M. A. Obolenskii +7

$M (B)$ -curves were experimentally investigated. Fishtail-effect (FE) was observed in MG YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ and YBa $_{2}$ (Cu $_{1 - x}$ Ag $_{x}$ ) $_{3}$ O $_{7 - δ}$ (at $x \approx$ 0.02) crys…
