We have synthesized oligopeptides based on insect silks with added metal ion complexing groups at the ends of the oligopeptides. These oligopeptides can be complexed with magnetic ions and used to chemically deliver them into a pattern of nanoscale magnetic ion-rich layers without thin-film deposition. Gd-, Dy-, and Cr-complexed oligopeptide materials were studied and were found to be well-behaved paramagnets. With higher concentrations of magnetic ions, magnetic coupling interactions may be possible. [ABSTRACT FROM AUTHOR]

The rare-earth ruthenate Pr[sub 3]RuO[sub 7] is a Mott insulator displaying magnetic ordering at two temperatures T[sub N1] = 36 K and T[sub N2] = 55 K. By substituting diamagnetic La for Pr and diamagnetic Nb for Ru, T[sub N1] is shown to be associated with ordering among the rare earths and T[sub N2] among the Ru cations. These results are similar to those of Sm[sub 3]RuO[sub 7], but the ordering temperatures for Pr[sub 3]RuO[sub 7] are large compared with all other known Ln[sub 3]MO[sub 7] systems and there is less divergence between field-cooled and zero-field-cooled magnetic susceptibility for T < T[sub N2]. Isothermal magnetization measurements, including pulsed-field measurements, show hysteretic-field-induced transitions at B ≈ 4T for T ≪ T[sub N1] associated with a spin reorientation of the Pr moments. Further characterization of Pr[sub 3]RuO[sub 7] is provided from measurements of the heat capacity for 2 K < T < 17 K and electrical resistivity for 100 K < T < 300 K. [ABSTRACT FROM AUTHOR]
