The magnetization of Fe/Pt multilayers has been measured as a function of temperature. A bulk-like T3/2 temperature dependence of the magnetization is observed for all multilayers in the temperature range 5–300K. The spin wave constant B is found to decrease inversely with tFe. A simple...

Optical photometric measurements in the visible range (1.4–5.4 eV) under oblique incidence have been performed on Ag/SiO2 periodic multilayers prepared by magnetron sputtering. The results are discussed in terms of radiative virtual modes due to the Ag layers. The fundamental radiative mode is...

We consider random walks, starting at the site i = 1, on a one-dimensional lattice segment with an absorbing boundary at i = 0 and a reflecting boundary at i = L. We find that the typical value of first passage time (FPT) is independent of system size L, while the mean value diverges linearly...

The magnetization of Fe(10Å)/V(tV) (10Å⩽tV⩽ 40Å) multilayers has been measured as a function of temperature. For Fe/V multilayers with fixed iron layer thickness of 10Å, the magnetization decreases faster with temperature as the vanadium layers are made thicker. A simple theoretical...
