We report results of susceptibility χ and <Superscript>7</Superscript>Li NMR measurements on LiVSi<Subscript>2</Subscript>O<Subscript>6</Subscript>. The temperature dependence of the magnetic susceptibility χ(T) exhibits a broad maximum, typical for low-dimensional magnetic systems. Quantitatively it is in agreement with the expectation for an S=1 spin chain,...</subscript></subscript></superscript>

Zero-field nuclear magnetic resonance (NMR) of all NMR isotopes (<Superscript>175</Superscript>Lu, <Superscript>55</Superscript>Mn, <Superscript>73</Superscript>Ge, <Superscript>69,71</Superscript>Ga) in LuMn<Subscript>6</Subscript>Ge<Subscript>6-x</Subscript>Ga<Subscript>x</Su bscript>, 0 ≤ x ≤ 1, is used to monitor the variation of the hyperfine interaction with the sequence of antiferromagnetic - helimagnetic - ferromagnetic arrangement of the manganese moments...<//su></subscript></subscript></subscript></superscript></superscript></superscript></superscript>

In this contribution we report on the plastic crystal 1-chloroadamantane dynamics via conventional frequency dependent (<Superscript>1</Superscript>H and <Superscript>13</Superscript>C) and field cycling NMR measurements. A suitable microscopic dynamical model, worked out from from X-ray analysis is developed and the molecular motions are...</superscript></superscript>

We report on a nuclear magnetic resonance (NMR) study of ultrananocrystalline diamond (UNCD) materials produced by detonation technique. Analysis of the <Superscript>13</Superscript>C and <Superscript>1</Superscript>H NMR spectra, spin-spin and spin-lattice relaxation times in purified UNCD samples is presented. Our measurements show that UNCD...</superscript></superscript>

In a magnetic field, spin-ladders undergo two zero-temperature phase transitions at the critical fields H<Subscript>c1</Subscript> and H<Subscript>c2</Subscript>. An experimental review of static and dynamical properties of spin-ladders close to these critical points is presented. The scaling functions, universal to all quantum critical...</subscript></subscript>
