We report the first μSR measurements done on a cluster of monodisperse Pd nanoparticles. The measurements give access to the dipole field from the unpaired electron magnetic moments. We find for a two shell compound that the field is smaller than ex

Iron, nickel and cobalt nanowires are prepared within the pores of nanoporous alumina membranes using an electrochemical AC plating procedure. Nanowires produced in this way can be easily varied in diameter (5–250 nm) and length (up to several hund

We present an extensive study of the magnetic reversal mechanism of Fe and Ni nanowires with diameters down to 6 nm, i.e. smaller than the domain wall width. The coercive field at 5 K is a factor of 3 lower than the prediction for rotation in unison.

We present a detailed Mossbauer study of a series of Au and Pt particles in the size range from 1 to 17 nm. All measured spectra can be explained consistently with a refined model, in which the Mossbauer isomer shift varies in the inner core of a sma

The influence of the cation on the electronic properties of coordination compounds with Ni(dmit)2 anions has been studied in the new series (MexGua)[Ni(dmit)2]2, where x = 0, 2, 4, 6. In the tight-binding analysis a two-orbital approach appears to be

The magnetization reversal and magnetic anisotropy of Fe, Ni and Co nanowires is studied at low temperatures. All nanowires show a strong shape anisotropy with the easy axis being parallel to the long axis of the wires. Co nanowires additionally show

155 Gd and 157 Gd NMR of intermetallics GdGa 2- x Al x has been observed at low temperature for x less than 0.5. The spectra were spread very broadly from 10 to 110 MHz due to large electric field gradient and quadrupole moments of gadrinium nuclei.

We present a detailed experimental study of Fe and Co colloidal particles stabilized by organic ligands. Comparison is made between the magnetic properties of pure and gold-coated particles. In all cases, evidence of superparamagnetic behaviour is fo
