We have carried out $^{63,65}\mathrm{Cu}$ NMR spectra measurements in a magnetic field up to about 45 T on a single crystal of a multiferroic triangular antiferromagnet ${\mathrm{CuCrO}}_{2}$. The measurements were performed for magnetic fields align

Transitions associated with orientational order–disorder phenomena are found in a wide range of materials and may have a significant impact on their properties. In this work, specific heat and 1 H NMR measurements have been used to study the phase

We have performed NMR experiments on the quasi one-dimensional frustrated spin-1/2 system LiCuVO$_4$ in magnetic fields $H$ applied along the c-axis up to field values near the saturation field $H_{\rm sat}$. For the field range $H_{\rm c2} 41.4$T, i

We report on NMR studies of the quasi one--dimensional (1D) antiferromagnetic $S=1/2$ chain cuprate LiCuVO$_4$ in magnetic fields $H$ up to $\mu_0H$ = 30 T ($\approx 70$% of the saturation field $H_{\rm sat}$). NMR spectra in fields higher than $H_{\

Hydrogenated nano-crystalline silicon (nc-Si:H) is a promising material for multi-junction solar cells. We investigated the local hydrogen environments in nano-crystalline silicon thin films by nuclear-magnetic-resonance (NMR). At room temperature, 1

We report on pulsed-field magnetization, $Q$-band electron spin resonance (ESR), and $^{23}\mathrm{Na}$ NMR measurements of the $S=1∕2$ spin triangle clusters ${\mathrm{Na}}_{9}[{\mathrm{Cu}}_{3}{\mathrm{Na}}_{3}{({\mathrm{H}}_{2}\mathrm{O})}_{9}{(

Experimental and ab initio molecular orbital techniques are developed for study of aluminum species with large quadrupole coupling constants to test structural models for methylaluminoxanes (MAO). The techniques are applied to nitrogen- and oxygen-co

Spectra of nonspinning samples with large quadrupole coupling constants, 16–32 MHz, are acquired by frequency-stepping. A series of spin-echoes are acquired at arbitrary frequency increments, frequency-shifted in the time domain, and co-added as ma
