Growth conditions, structure, and superconductivity of pure and metal-doped FeTe1-xSex single crystals
Dariusz Jakub Gawryluk,Jan Fink-Finowicki,A. Wisniewski,Roman Puzniak,Viktor Domukhovski,R. Diduszko,Mirosław Kozłowski,Marek Berkowski +7 more
TL;DR: In this paper, it was found that the sharpness of transition to the superconducting state in FeTe1 xSex is evidently inversely correlated with crystallographic quality of the crystals.

Growth conditions, structure and superconductivity of pure and metal-doped FeTe1-xSex single crystals
Dariusz Jakub Gawryluk,Jan Fink-Finowicki,Andrzej Wiśniewski,R. Puźniak,Viktor Domukhovski,R. Diduszko,Mirosław Kozłowski,Marek Berkowski +7 more
TL;DR: In this article, it was found that the sharpness of the transition to the superconducting state in FeTe1 − xSex is evidently inversely correlated with the crystallographic quality of the crystals.
Journal ArticleDOI
Pressure-tuned spin state and ferromagnetism in La 1 − x M x Co O 3 ( M = Ca , Sr )
I. M. Fita,I. M. Fita,R. Szymczak,Roman Puzniak,I. O. Troyanchuk,Jan Fink-Finowicki,Ya. M. Mukovskii,V. N. Varyukhin,H. Szymczak +8 more
TL;DR: In this article, the authors studied the effect of pressure on magnetic order and anisotropy of low-doped materials and found that applied hydrostatic pressure leads to a quite different effect on ferromagnetic (FM) interactions in materials doped with ions of different size.
Journal ArticleDOI
Magnetic field-induced transitions in geometrically frustrated Co 3 V 2 O 8 single crystal
TL;DR: In this paper, the magnetic field induced phase transitions observed for various orientations of magnetic field were investigated as a function of temperature and magnetic field and it was suggested that the jump, observed for $H\ensuremath{-parallel}\mathbit{c}$-axis have been observed below $6\phantom{\rule{0.3em}{0ex}}\mathrm{K}$.
Journal ArticleDOI
Influence of magnetic field on the paramagnetic-ferromagnetic transition in a La 1 − x Ca x Mn O 3 ( x ≈ 0.25 ) crystal: Ultrasonic and transport studies
B. I. Belevtsev,G. A. Zvyagina,K. R. Zhekov,I. G. Kolobov,E. Yu. Beliayev,A. S. Panfilov,N. N. Galtsov,A. I. Prokhvatilov,Jan Fink-Finowicki +8 more
TL;DR: In this article, the magnetic field influence on sound velocities was investigated. But the magnetic-ferromagnetic transition in the sample studied is first order, but can become second order under the influence of applied magnetic field.
