Abstract

Nanometer-scale ferromagnetic particles (Fe[sub 2]O[sub 3], Fe[sub 3]O[sub 4]) are dispersed within a mutant bacterial chain which is drawn into a macroscopic fiber “rope.” Cross-sectional scanning electron microscopy images reveal that the iron oxide particles are intercalated between the walls of the bacterial cells which are bundled into parallel threads. The field-dependent switching is seen to markedly sharpen when the synthesis is conducted within an applied magnetic field. © 1998 American Institute of Physics. [ABSTRACT FROM AUTHOR]
