Collinear order and chirality-reorientation transition in the Cairo pentagonal magnet BiFeOF
Alexander A. Tsirlin, Ioannis Rousochatzakis, Dmitry Filimonov +3
We show that interlayer spins play a dual role in the Cairo pentagonal magnet BiFeOF, on one hand mediating the three-dimensional (3D) magnetic order and on the othe…
Establishing the fundamental magnetic interactions in the chiral skyrmionic Mott insulator Cu2OSeO3 by terahertz electron spin resonance
M. Ozerov, J. Romhányi, M. Belesi +6
The recent discovery of skyrmions in CuOSeO has established a new platform to create and manipulate skyrmionic spin textures. We use high-field electron spin resonance (ESR…
Kitaev interactions between j=1/2 moments in honeycomb Na2IrO3 are large and ferromagnetic: insights from ab initio quantum chemistry calculations
Vamshi M. Katukuri, S. Nishimoto, V. Yushankhai +7
NaIrO, a honeycomb 5 oxide, has been recently identified as a potential realization of the Kitaev spin lattice. The basic feature of this spin model is that for each o…
Magnetoelectric effects in single crystals of the cubic ferrimagnetic helimagnet Cu2OSeO3
M. Belesi, I. Rousochatzakis, M. Abid +3
We present magnetodielectric measurements in single crystals of the cubic spin-1/2 compound CuOSeO. A magnetic field-induced electric polarization () and a finite…
Decorated Shastry-Sutherland lattice in the spin-1/2 magnet CdCu2(BO3)2
O. Janson, I. Rousochatzakis, A. A. Tsirlin +3
We report the microscopic magnetic model for the spin-1/2 Heisenberg system CdCu2(BO3)2, one of the few quantum magnets showing the 1/2-magnetization plateau. Recent neutron diffra…
Transmission Losses in Left-handed Materials
P. markos, I. Rousochatzakis, C. M. Soukoulis
We numerically analyze the origin of the transmission losses in left-handed structures. Our data confirms that left handed structures can have very good transmission properties, in…
