The iron-based high temperature superconductors exhibit a rich phase diagram reflecting a
complex interplay between spin, lattice, and orbital degrees of freedom. The nematic state …

TmVO4 exhibits ferroquadrupolar order of the Tm 4f electronic orbitals at low temperatures,
and is a model system for Ising nematicity. A magnetic field oriented along the c-axis …

High-temperature superconductivity in Fe-based pnictides and chalcogenides has been one
of the most significant recent discoveries in condensed matter physics and has attracted …

Ferroquadrupole order of local atomic orbitals provides a specific realization of electronic
nematic order. TmVO 4 is an insulator and undergoes ferroquadrupolar order associated …

The NMR spectrum of FeSe shows a dramatic broadening on cooling towards the bulk
nematic phase at T s= 90 K, due to the formation of a quasistatic, short-range-ordered …

We investigate the effectiveness of the Inverse Laplace Transform (ILT) analysis method to
extract the distribution of relaxation rates from nuclear magnetic resonance data with …

Isotope Sb 121, 123 nuclei with large electric quadrupole moments are applied to
investigate the dynamics of orbital degrees of freedom in Sb-substituted iron (Fe)-based …

The origin of nematic order remains one of the major debates in iron-based
superconductors. In theories based on spin nematicity, one major prediction is that the spin …

As 75 NMR measurements have been made on single crystals to study the nematic state in
the iron arsenides NaFeAs, which undergoes a structural transition from a high-temperature …
