The magnetic properties of Pt/Co/Pt sandwiches prepared by sputtering onto Al 2 O 3 (0 0 0 1) single crystal substrates have been investigated in relation with their structure. Co island coalescence is completed before deposition of 40 A of Pt. The s

We report polarized Raman scattering in single crystals of Nd0.7Sr0.3MnO3. The temperature dependence of the MnO6 octahedral bending and stretching modes observed in the XX spectra points to the existence of local lattice distortions, possibly polaro

A displacive, 2nd order structural phase transition at Ts=395 K from space group I`4 2 m below Ts to I 4/m c m above Ts has been discovered in the two-dimensional spin dimer compound SrCu2(BO3)2. The temperature evolution of the structure in both pha

The pinning of flux lines by two different types of regular arrays of submicron magnetic dots is studied in superconducting Pb films; rectangular Co dots with in-plane magnetization are used as pinning centers to investigate the influence of the magn

We study the reflection and transmission of a spacer Bloch-wave at a magnetic layer of finite thickness. The layer has a composite structure obtained by attaching an adlayer to the magnetic layer. The emphasis of this paper will lay on the change of

Low energy Raman scattering of the s=1/2 spin tetrahedra system Cu_2Te_2O_5Br_2 is dominated by an excitation at 18 cm^{-1} corresponding to an energy E_S=0.6\Delta, with \Delta the spin gap of the compound. For elevated temperatures this mode shows
