Two-dimensional magnetism in kappa-(BEDT-TTF)2Cu[N(CN)2]Cl, a spin-1/2 Heisenberg antiferromagnet with Dzyaloshinskii-Moriya interaction

Autor: Antal, Ágnes, Fehér, Titusz, Náfrádi, Bálint, Forró, László, Jánossy, András

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-TTF)_2Cu[N(CN)_2]Cl, a quasi two-dimensional antiferromagnet with a lar

Autor: Fábián, Gábor, Dóra, Balázs, Antal, Ágnes, Szolnoki, Lénárd, Korecz, László, Rockenbauer, Antal, Nemes, Norbert M., Forró, László, Simon, Ferenc

Publikováno v: Phys. Rev. B 85, 235405 (2012)

Temperature dependent electron spin resonance (ESR) measurements are reported on stage 1 potassium doped graphite, a model system of biased graphene. The ESR linewidth is nearly isotropic and although the g-factor has a sizeable anisotropy, its major

Spin diffusion and magnetic eigenoscillations confined to single molecular layers in the organic conductors kappa-(BEDT-TTF)_2Cu[N(CN)_2X (X=Cl, Br)

Autor: Antal, Agnes, Feher, Titusz, Janossy, Andras, Tatrai-Szekeres, Erzsebet, Fulop, Ferenc

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 insulator while the isostructural Br compound is a superconductor. We find
