Electromagnon dispersion probed by inelastic X-ray scattering in LiCrO2

Henrik Moodysson Rønnow, Christian Rüegg, Sándor Tóth

Inelastic X-ray scattering with meV energy resolution (IXS) is an ideal tool to measure collective excitations in solids and liquids. In non-resonant scattering condition, the cross-section is strongly dominated by lattice vibrations (phonons). However, it ...

Jahn-Teller versus quantum effects in the spin-orbital material LuVO3

Paul Gregory Freeman, Sándor Tóth, Mechthild Enderle

We report on combined neutron and resonant x-ray scattering results, identifying the nature of the spin-orbital ground state and magnetic excitations in LuVO3 as driven by the orbital parameter. In particular, we distinguish between models based on orbital ...

Spiral magnetic phase in Li-doped Na2IrO3

Sándor Tóth, Kazimierz Conder

The doping of the honeycomb lattice compound Na2IrO3 with cations having smaller ionic radius such as lithium was supposed to drive the system into a Kitaev spin liquid phase. Even at the smallest doping level the long range magnetic order, present in the ...

Linear spin wave theory for single-Q incommensurate magnetic structures

Sándor Tóth

Linear spin wave theory provides the leading term in the calculation of the excitation spectra of long-range ordered magnetic systems as a function of 1/root S. This term is acquired using the Holstein-Primakoff approximation of the spin operator and valid ...

Enhanced thermal stability and spin-lattice relaxation rate of N@C-60 inside carbon nanotubes

László Forró, Bálint Náfrádi, Sándor Tóth

We studied the temperature stability of the endohedral fullerene molecule N@C-60 inside single-wall carbon nanotubes using electron-spin-resonance spectroscopy. We found that the nitrogen escapes at higher temperatures in the encapsulated material as compa ...

Stability and electronic properties of magnetic peapods

László Forró, Bálint Náfrádi, Sándor Tóth

We report on the temperature stability of N@C-60 peapods using electron spin resonance. The atomic nitrogen escapes at higher temperatures in the peapod than in the crystalline form. We also report on the synthesis of novel magnetic fullerene peapod, a ful ...
