The microscopic magnetism of BaVS3, which undergoes a metal-insulator transition at TMI = 70K, has been investigated by using V nuclear resonance and neutron scattering. At 1.4K, we observed zero-field resonance signals in a low-frequency range, which were interpreted as being NQR, i.e., the absence of a static hyperfine field. On the other hand, we found magnetic Bragg peaks below 30K, indicat...

We present electrically detected electron nuclear double resonance measurements of the nuclear spins of ionized and neutral arsenic donors in strained silicon. In addition to a reduction of the hyperfine coupling, we find significant quadrupole interactions of the nuclear spin of the neutral donors of the order of 10 kHz. By comparing these to the quadrupole shifts due to crystal fields measure...

2014 Incoherent neutron quasi-elastic scattering (NQES), 14N nuclear quadrupole resonance (NQR) and deuterium nuclear magnetic resonance (DMR) data in the smectic VI, smectic H, smectic C, smectic A and nematic phases of terephtal-bis-butyl-aniline (TBBA) are analysed consistently in terms of simple rotational models allowing both orientational order around the long molecular axis and fluctuati...
