FRANKEL Abstract A brackish lagoon at Itaipu, Brazil, contains magnetotactic bacteria with unusually large magnetite magnetosomes (lengths 100–200 nm). The micromagnetic structures of the magnetosomes from two different...

...-dimensional arrangement of the crystals in the multiple greigite chain ( Kasama et al. 2006 ). To date, the magnetic moments of magnetosome chains in three different strains of magnetite-producing bacteria (MS-1 and MV-1, Dunin-Borkowski et al. 1998 , 2001 ; Itaipu-1, McCartney et al. 2001 ) and in two...
