Magnetoresistance measurements are used to identify the spin-flip transition temperature Tsf in 500 and 3000 A thick Cr(001) films grown epitaxially on LiF(001). Tsf is suppressed to a lower temperature in the 500 A film compared to the bulk value of

We report magnetothermopower S(H) measurements at room temperature for sputtered [Fe(32 A) / Cr(x)]30 superlattices with x ≈ 5–50 A. The thermopower in zero field S(H = 0) appears to extrapolate to the known values for Fe and Cr in the x = 0 and

The modulation wavelength dependence of the surface‐wave velocity in Cu/Ni superlattices has been investigated using Brillouin scattering. It is the first compositionally modulated system to be studied by this technique and the first for which elas

We report the results of transport measurements on epitaxial Cr thin films. The variation of TN (The Neel transition temperature) with respect to the film thickness is discussed in terms of the stress in the film. In addition, the temperature depende

A review is given of the magnetic properties of metallic actinides, and of the relationship between their properties and their electronic structures. It is shown that the 5f electrons of light actinides often form into bands, rather than exist as loc

We have performed measurements of the de Haas-van Alphen (dHvA) effect in the intermetallic compound U${\mathrm{Rh}}_{3}$, a material with a partially filled $5f$ shell. Complex dHvA spectra containing several frequencies were observed and Fourier an

We report measurements of the specific heat, Moessbauer effect, and electrical resistivity of NpSn/sub 3/, which identify its weak antiferromagnetism (T/sub N/=9.5 K) as arising from itinerant 5f electrons. This is the first known verification of iti

We investigated exchange coupling of Fe layers across Au and Cr interlayers by means of light scattering from spin waves. For Au interlayers we find a continuous decrease of this coupling to zero as the Au thickness is increased from 0 to \ensuremath

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

Fe L/sub III/ and L/sub II/ electron-energy-loss spectra of amorphous alloys Fe/sub x/Ge/sub 1-x/ (0.2< or =x< or =0.6) have shown that there is no charge transfer between germanium and the iron d band, and a charge-transfer mechanism cannot be respo
