COBISS.SI-ID: 22719527In the diploma thesis we report the 23Na nuclear magnetic resonance study of the influence of pressure and doping level on the magnetic order and superconductivity in a member of the high-temperature iron-based superconductors NaxFeAs. We have discovered that the spin-lattice relaxation time T1 exhibits a power law behavior at high temperatures. We have successfully explained this dependency with the minimal model of three hole-like bands.

In the diploma thesis we employed nuclear magnetic resonance technique under high pressure conditions to study normal and superconducting state of Cs3C60 compound. For this purpose a high-pressure cell was designed and a new method for pressure measuring was developed, by means of which the phase diagram of fullerene Cs3C60 with face-centered cubic structure was explored.

We presented a detailed nuclear magnetic resonance (NMR) study of the normal state properties of LiFeAs, Na1FeAs and Na0.9FeAs polycrystalline samples, the so-called ‘111’ members of newly discovered family of Fe-based superconductors. Our NMR experiments demonstrate the absence of a structural phase transition and antiferomagnetic (AFM) ordering in LiFeAs down to Tc, whereas Na1FeAs and Na0.9FeAs, which are structural analogues of LiFeAs, show the AFM ordering at TN = 44 K and 50 K, respectively, with small Fe moment.
