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…

Evolution of Fishtail-effect with aging in pure and Ag-doped MG-YBCO

D. A. Lotnyk, R. V. Vovk, M. A. Obolenskii +6

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

Pseudogap state in slightly doped by aluminium and praseodymium YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ single crystals with a given topology of plane defects

R. V. Vovk, M. A. Obolenskii, A. A. Zavgorodniy +2

In present work the conductivity in the basis plane of YBaCuO single crystals slightly doped by Al and Pr with a pre-specified topology of twin boundaries has been investigated. Th…

Order-disorder transition induced by deformation of vortex lines at the twin boundaries in YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ -crystals: test of the Lindemann criteria

Yu. T. Petrusenko, A. V. Bondarenko, A. A. Zavgorodniy +2

We show that rotation of the magnetic field off the plane of twin boundaries (TB's) induces transition of an ordered vortex solid phase to a disordered one. This transition arises…

Quasi-static and dynamic order-disorder transition in presence of strong pinning

A. V. Bondarenko, A. A. Zavgorodniy, D. A. Lotnik +3

We present the results of an experimental study of vortex dynamics in non-twinned $Y B a_{2} C u_{3} O_{6, 87}$ crystal. It is found that critical currents $J_{c}$ and $J_{c, d y n}$ , which corre…
