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…
Multipurpose High Frequency Electron Spin Resonance Spectrometer for Condensed Matter Research
Kalman L Nagy, Dario Quintavalle, Titusz Feher +1
We describe a quasi-optical multifrequency ESR spectrometer operating in the 75-225 GHz range and optimized at 210 GHz for general use in condensed matter physics, chemistry and bi…
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…
Generalized Elliott-Yafet theory of electron spin relaxation in metals: the origin of the anomalous electron spin life-time in MgB2
F. Simon, B. Dora, F. Muranyi +6
The temperature dependence of the electron spin relaxation time in MgB2 is anomalous as it does not follow the temperature dependence of the resistivity above 150 K, it has a maxim…
Mg5C60: A stable two dimensional conducting polymer
D. Quintavalle, F. Borondics, G. Klupp +5
We present a study on the structural, spectroscopic, conducting and magnetic properties of Mg5C60, a two dimensional (2D) fulleride polymer. The polymer phase is stable up to the e…
Spin excitations in the antiferromagnet NaNiO2
Sophie De Brion, C. Darie, M. Hopzapfel +5
In NaNiO2, Ni3+ ions form a quasi two dimensional triangular lattice of S = 1=2 spins. The magnetic order observed below 20K has been described as an A type antiferromagnet with fe…
