We are studying Jahn-Teller (JT) effect in alkali-doped fullerene materials like RbxCs3-xC60, and MAK3C60 (MA = CH3NH2). We have shown that Jahn-Teller effect is completely dominated by strong steric effects in MAK3C60 (A. Potočnik, et al. PRB 2012).
We developed high-hydrostatic pressure probes for EPR (X-band) and NMR experiments. Our clamp-type cells can continuously reach up to 1.2 GPa and 2.5 GPa for EPR and NMR experiments, respectively. EPR high-pressure cell allows also measurements with pulse techniques. Anvil-type cells for achieving even higher pressures are currently being developed.
