Ferromagnetic Order, Strong Magnetocrystalline Anisotropy, and Magnetocaloric Effect in the Layered Telluride Fe3−δGeTe2
Valeriy Yu. Verchenko,Alexander A. Tsirlin,A. V. Sobolev,Igor A. Presniakov,Andrei V. Shevelkov +4 more
TL;DR: This work explores magnetic behavior and ensuing functional properties of Fe(2.9)GeTe2 via neutron diffraction, thermodynamic and transport measurements, Mössbauer spectroscopy, and electronic structure calculations, which reveal a remarkably high easy-axis anisotropy of 4.2 meV/f.
Journal ArticleDOI
Sn20.5□3.5As22I8: A Largely Disordered Cationic Clathrate with a New Type of Superstructure and Abnormally Low Thermal Conductivity
Julia V. Zaikina,Kirill Kovnir,A. V. Sobolev,Igor A. Presniakov,Y. Prots,Michael Baitinger,Walter Schnelle,Andrei V. Olenev,Oleg I. Lebedev,Gustaaf Van Tendeloo,Yuri Grin,Andrei V. Shevelkov +11 more
TL;DR: In this article, a new cationic clathrate, Sn(20.5)As(22)I(8), has been prepared by using an ampoule technique, and it crystallizes in the face-centered cubic space group F23 or Fm(-)3 with a unit-cell parameter of a=22.
Journal ArticleDOI
Sn19.3Cu4.7As22I8: a New Clathrate-I Compound with Transition-Metal Atoms in the Cationic Framework
Kirill Kovnir,A. V. Sobolev,Igor A. Presniakov,Oleg I. Lebedev,Gustaaf Van Tendeloo,Walter Schnelle,Yuri Grin,Andrei V. Shevelkov +7 more
TL;DR: Though containing a transition metal, Sn19.3Cu4.7As22I8 does not contain vacancies in the framework but reveals three partially occupied positions of the metal atoms, leading to the formation of Sn-Sn and Sn-Cu bonds that differ in length.
Journal ArticleDOI
Crystal structure, physical properties, and electronic and magnetic structure of the spin S = 5/2 zigzag chain compound Bi2Fe(SeO3)2OCl3.
Peter S. Berdonosov,E. S. Kuznetsova,Valery A. Dolgikh,A. V. Sobolev,Igor A. Presniakov,Andrei V. Olenev,Badiur Rahaman,Tanusri Saha-Dasgupta,K. V. Zakharov,Elena A. Zvereva,Olga S. Volkova,Olga S. Volkova,Alexander N. Vasiliev,Alexander N. Vasiliev,Alexander N. Vasiliev +14 more
TL;DR: In this paper, the synthesis and characterization of the new bismuth iron selenite oxochloride Bi2Fe(SeO3)2OCl3 was reported.
Journal ArticleDOI
