Magnet, nanoscale

Several striking examples demonstrating the atomically precise control exercised by the STM have been reported. A "quantum corral" of Fe atoms has been fabricated by placing 48 atoms in a circle on a flat Cu(lll) surface at 4K (Fig. 4) (94). Both STM (under ultrahigh vacuum) and atomic force microscopy (AFM, under ambient conditions) have been employed to fabricate nanoscale magnetic mounds of Fe, Co, Ni, and CoCr on metal and insulator substrates (95). The AFM has also been used to deposit organic material, such as octadecanethiol onto the surface of mica (96). New appHcations of this type of nanofabrication ate being reported at an ever-faster rate (97—99). [Pg.204]

Various experimental methods have been developed for investigating the magnetoelastic properties of thin films and nanoscale magnetic systems. In the following subsections, we discuss the most important ones (i) the magnetoelastic cantilever, (ii) strain induced anisotropy, (iii) magnetostriction in spin valves, (iv) strain modulated ferromagnetic resonance, (v) secondary-electron spin-polarisation, and (vi) strain-induced anisotropy due to the spontaneous strains.

It has been shown, both experimentally and theoretically (see [5] for details), that the magnetoelastic tensor [5] in nanoscale magnetic multilayers consists of two parts ... [Pg.247]

Patterned media (e.g. section 4.1) can be fabricated from magnetic multilayers where ion irradiation is used to differentiate nanoscale magnetic islands in a magnetic matrix, without the removal of material from the multilayers [15, 16]. Arrays of Pt/Co/Pt dots with a dot separation of only 20 nm have been shown by FIB irradiation of 28keV Ga+ ions [17]. The magnetic effects can be influenced by the kinds of ions (He+, Ar+, Ga+, N+), their energies as well as their exposure doses (fluency). [Pg.265]

Many materials exist that have dimensions in the range of 1 rnn to several micrometers. Recall that colloidal particles (e.g., latex particles from emulsion polymerization, colloidal silica or alumina, etc.) fall in the range from about 10 nm to 1000 nm (1 jxm). A few examples of nanoparticles that are designed with more specific structures or geometries include carbon nanotubes, metal clusters, nanoscale magnetic crystals, and semiconducting ... [Pg.209]
