Reversible Behavior in 17nm Fe3O4Capped Janus ParticlesA. Ruditskiy, I. Kretzschmar – City College of New YorkDMR# 0934206 B = 0.08 Tesla Vpp = 4.5 V B = 0.08 Tesla Vpp reduced to 1.0 V B = 0.08 Tesla Vpp reduced to 0.25 V B = 0.08 Tesla Vpp increased to 1.0 V staggered chain partial double chain double chain partial staggered chain The structure transitions from staggered to loose double chain configuration as the voltage is ramped down at constant magnetic field. As the voltage is ramped back up the structure reforms and the staggered character begins to re-emerge.
