Electronic and ionic conductivities in superionic LiC
D. Quintavalle, B. G. Márkus, A. Jánossy +7
The GHz microwave conductivity, and high field, GHz electron spin resonance (HF-ESR) of LiC fulleride is measured in a wide temperature range. We sugge…
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…
Enhanced thermal stability and spin-lattice relaxation rate of N@C60 inside carbon nanotubes
S. Toth, D. Quintavalle, B. Nafradi +3
We studied the temperature stability of the endohedral fullerene molecule, N@C60, inside single-wall carbon nanotubes using electron spin resonance spectroscopy. We found that the…
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…
Phase segregation on the nanoscale in Na2C60
G. Klupp, P. Matus, D. Quintavalle +6
Na2C60 is believed to be an electron-hole counterpart of the Mott-Jahn--Teller insulator A4C60 salts. We present a study of infrared, ESR, NMR spectroscopy, X-ray diffraction, chem…
