Peierls distortion, magnetism, and high hardness of manganese tetraboride
Huiyang Gou, Alexander A. Tsirlin, Elena Bykova +10
We report crystal structure, electronic structure, and magnetism of manganese tetraboride, MnB4, synthesized under high-pressure high-temperature conditions. In contrast to superco…
Discovery of a superhard iron tetraboride superconductor
Huiyang Gou, Natalia Dubrovinskaia, Elena Bykova +11
Single crystals of novel orthorhombic (space group Pnnm) iron tetraboride FeB4 were synthesised at pressures above 8 GPa and high temperatures. Magnetic susceptibility measurements…
Frustrated pentagonal Cairo lattice in the non-collinear antiferromagnet Bi4Fe5O13F
Artem M. Abakumov, Dmitry Batuk, Alexander A. Tsirlin +6
The crystal and magnetic structures and underlying magnetic interactions of Bi4Fe5O13F, a model system for studying the physics of the Cairo pentagonal spin lattice, are investigat…
(CuCl)LaTa2O7 and quantum phase transition in the (CuX)LaM2O7 family (X = Cl, Br; M = Nb, Ta)
Alexander A. Tsirlin, Artem M. Abakumov, Clemens Ritter +1
We apply neutron diffraction, high-resolution synchrotron x-ray diffraction, magnetization measurements, electronic structure calculations, and quantum Monte-Carlo simulations to u…
Short-range order of Br and three-dimensional magnetism in (CuBr)LaNb2O7
Alexander A. Tsirlin, Artem M. Abakumov, Clemens Ritter +3
We present a comprehensive study of the crystal structure, magnetic structure, and microscopic magnetic model of (CuBr)LaNb2O7, the Br analog of the spin-gap quantum magnet (CuCl)L…
Phase separation and frustrated square lattice magnetism of Na1.5VOPO4F0.5
A. A. Tsirlin, R. Nath, A. M. Abakumov +7
Crystal structure, electronic structure, and magnetic behavior of the spin-1/2 quantum magnet Na1.5VOPO4F0.5 are reported. The disorder of Na atoms leads to a sequence of structura…
Spiral ground state against ferroelectricity in the frustrated magnet BiMnFe2O6
Artem M. Abakumov, Alexander A. Tsirlin, Juan Manuel Perez-Mato +4
The spiral magnetic structure and underlying spin lattice of BiMnFe2O6 are investigated by low-temperature neutron powder diffraction and density functional theory band structure c…
Interplay of atomic displacements in the quantum magnet (CuCl)LaNb2O7
Alexander A. Tsirlin, Artem M. Abakumov, Gustaaf Van Tendeloo +1
We report on the crystal structure of the quantum magnet (CuCl)LaNb2O7 that was controversially described with respect to its structural organization and magnetic behavior. Using h…
