Assembly Behavior of Iron Oxide-Capped Janus Particles in a Magnetic Field
Three types of iron oxide Janus particles are obtained
by varying
the deposition rate of iron in a 3:1 Ar/O<sub>2</sub> atmosphere during
physical vapor deposition. Each type of iron oxide Janus particle
shows a distinct assembly behavior when an external magnetic field
is applied, i.e., formation of staggered chains, double chains, or
no assembly. A detailed deposition rate diagram is obtained to identify
the relationship between deposition rate and assembly behavior. The
extent of iron oxidation is identified as the key parameter in determining
the assembly behavior. In addition, the effects of particle volume
fraction, thickness of
the iron oxide cap, and assembly time on the final assembly behavior
are studied. Cap thickness is shown not to influence the assembly
behavior, while particle volume fraction and assembly time affect
the chain growth rate and the chain length, but not the overall assembly
behavior. The samples are characterized by optical, scanning electron,
and atomic force microscopies
