Microscopic model for the ground state, 1/3 plateau and excitations of -Mn(PO)
P. A. Maksimov, L. V. Shvanskaya, O. S. Volkova +1
We present a magnetic model for an antiferromagnetic compound -Mn(PO), which was previously shown to exhibit a 1/3 magnetization plateau due to the trimer-based stru…
Two-step phase transitions in Fe(Se,Te)
D. A. Chareev, A. A. Gippius, Y. A. Ovchenkov +6
In the studied crystals of FeSe0.7 Te0.3 , a structural phase transition occurs in two stages. At higher temperatures, the electronic subsystem undergoes a reconstruction, leading…
Multiband effect in elastoresistance of Fe(Se,Te)
Y. A. Ovchenkov, D. A. Chareev, D. E. Presnov +3
We have investigated the elastoresistance of two FeSeTe (x about 0.4 - 0.5) compounds that have a close chemical composition but differ significantly in electroni…
Majority carrier type inversion in FeSe family and "doped semimetal" scheme in iron-based superconductors
Y. A. Ovchenkov, D. A. Chareev, V. A. Kulbachinskii +5
The field and temperature dependencies of the longitudinal and Hall resistivity have been studied for high-quality FeSeS (x up to 0.14) single crystals. Quasiclas…
Magnetotransport properties of FeSe in fields up to 50T
Y. A. Ovchenkov, D. A. Chareev, V. A. Kulbachinskii +5
Magnetotransport properties of the high-quality FeSe crystal, measured in a wide temperature range and in magnetic fields up to 50 T, show the symmetry of the main holelike and ele…
Hybridization and spin-orbit coupling effects in quasi-one-dimensional spin-1/2 magnet Ba3Cu3Sc4O12
D. I. Badrtdinov, O. S. Volkova, A. A. Tsirlin +3
We study electronic and magnetic properties of the quasi-one-dimensional spin-1/2 magnet Ba3Cu3Sc4O12 with a distinct orthogonal connectivity of CuO4 plaquettes. An effective low-e…
Superconducting properties of sulfur-doped iron selenide
Mahmoud Abdel-Hafiez, Yuan-Yuan Zhang, Zi-Yu Cao +8
The recent discovery of high-temperature superconductivity in single-layer iron selenide has generated significant experimental interest for optimizing the superconducting properti…
Magnetic properties of the low-dimensional spin-1/2 magnet α-Cu_2As_2O_7
Y. C. Arango, E. Vavilova, M. Abdel-Hafiez +11
In this work we study the interplay between the crystal structure and magnetism of the pyroarsenate α-Cu_2As_2O_7 by means of magnetization, heat capacity, electron spin resonance…
