X-ray diffraction and calorimetry data on cubic NaxC60(1<<em>xTm above that of pure C60, e.g., Tm(x=1.3)=325 K. The ordered phases are the same as in pure C60: simple cubic, space group Pa3 Ì„, butâ€¦ (More)

We calculate electrostatic multipole moments of C60 up to l=18 using the quantum-mechanical charge distribution with icosahedral symmetry obtained from ab initio calculations. It is found that theâ€¦ (More)

The origins of anisotropy in the effective spin Hamiltonian, describing the ground manifold of Hubbard models with spin-orbit interactions, are critically discussed. For tetragonal symmetry, we showâ€¦ (More)

Here we correct, extend, and clarify results concerning the spin Hamiltonian HS used to describe the ground manifold of Hubbard models for magnetic insulators in the presence of spin-orbitâ€¦ (More)

We performed total uterine mucosal ablation (TUMA), a laparoscopic-assisted alternative to hysteroscopic endometrial ablation, in 10 women (mean age 41.2 yrs, mean parity 3.7) with therapy-resistantâ€¦ (More)

The spin Hamiltonian of tetragonal lamellar antiferromagnets is shown to contain several novel anisotropies. Symmetry allows bond-dependent anisotropic exchange interactions, which lead to (a)â€¦ (More)

Quantum effects on magnetic ordering in body-centered-tetragonal antiferromagnets with only nearestneighbor interactions are studied in detail using interacting spin-wave theory. The model consistsâ€¦ (More)

A symmetry analysis of the 2a phase recently observed in some samples of C60 is presented. This phase is described by a unit cell with eight molecules in inequivalent orientations. We first show thatâ€¦ (More)
