We studied the finite-size effect on the first-order metal-insulator phase transition and the accompanying tetragonal-to-monoclinic structural transition of ${\mathrm{VO}}_{2}$ films. The ${\mathrm{VO}}_{2}$ films were epitaxially grown by a metal-or

Electronic structure and energetics of (0001) and (11\ifmmode\bar\else\textasciimacron\fi{}02) surfaces of sapphire, \ensuremath{\alpha}-${\mathrm{Al}}_{2}$${\mathrm{O}}_{3}$, were calculated using the self-consistent-field discrete variational (DV)

Data are presented showing that the addition of B to ${\mathrm{URh}}_{3}$, which is well known to be a compound having itinerant f electrons, results in a localization of those f electrons and a narrowing of the 5f band. Band-structure calculations c

The electronic structure of some rare-earth orthovanadates, RVO/sub 4/, where R = La, Ce, Nd, Eu, Tb, Dy, or Yb, has been studied using the discrete variational X..cap alpha.. method. Charge and spin densities and the derived potentials for clusters

Magnetization measurements on single crystals of $\mathrm{Y}{\mathrm{Ba}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7\ensuremath{-}\ensuremath{\delta}}$ show strong anisotropic flux pinning with critical magnetization current densities of 1.4\ifmmode\times\e

The large conduction-electron polarization observed in many intermetallic actinide compounds with well localized $5f$ moments is analyzed using a phenomenological model for the electron density of states. The model is applied to PuP and successfully

The magnetic properties of the neptunium monopnictides, NpN, NpP, NpAs, and NpSb, have been examined by a variety of experimental techniques. All compounds have the NaCl structure. The present paper reports the results of magnetization, M\"ossbauer,
