Frustration induced one-dimensionality in the isosceles triangular antiferromagnetic lattice of -(EDT-TTF-CONMe)AsF
B. Náfrádi, A. Antal, T. Fehér +5
The -filled organic compound, -(EDT-TTF-CONMe)AsF is a frustrated two-dimensional triangular magnetic system as shown by high-frequency (111.2 and 222.4 GHz…
Two-dimensional magnetism in kappa-(BEDT-TTF)2Cu[N(CN)2]Cl, a spin-1/2 Heisenberg antiferromagnet with Dzyaloshinskii-Moriya interaction
Ágnes Antal, Titusz Fehér, Bálint Náfrádi +2
Field-induced antiferromagnetic (AF) fluctuations and magnetization are observed above the (zero-field) ordering temperature, T_N = 23 K by electron spin resonance in kappa-(BEDT-T…
Optical properties of the iron-pnictide analog BaMn2As2
A. Antal, T. Knoblauch, Y. Singh +3
We have investigated the infrared and Raman optical properties of BaMn2As2 in the ab-plane and along the c-axis. The most prominent features in the infrared spectra are the Eu and…
Spin-stretching modes in anisotropic magnets: spin-wave excitations in the multiferroic Ba2CoGe2O7
K. Penc, J. Romhányi, T. Rõõm +10
We studied spin excitations of the multiferroic Ba2CoGe2O7 in high magnetic fields up to 33 T. In the electron spin resonance and far infrared absorption spectra we found several s…
Origin of the ESR spectrum in the Prussian Blue analogue RbMn[Fe(CN)6]*H2O
Á. Antal, A. Jánossy, L. Forró +3
We present an ESR study at excitation frequencies of 9.4 GHz and 222.4 GHz of powders and single crystals of a Prussian Blue analogue (PBA), RbMn[Fe(CN)6]*H2O in which Fe and Mn un…
Spin diffusion and magnetic eigenoscillations confined to single molecular layers in the organic conductors kappa-(BEDT-TTF)_2Cu[N(CN)_2X (X=Cl, Br)
Agnes Antal, Titusz Feher, Andras Janossy +2
The layered organic compounds, kappa-(BEDT-TTF)_2Cu[N(CN)_2X (X=Cl, Br) are metals at ambient temperatures. At low temperatures, the Cl compound is a weakly ferromagnetic Mott insu…
