Magnetoelectric composites based on hexagonal ferrites

2011
Compósitos Magnetoelectricos baseados em ferrites hexagonais BaFe12O19, SrFe12O19, Ba3Co2Fe24O41, e em perovsquites ferroelectricas BaTiO3, foram estudadas. Foram realizadas análises estruturais por difracção de Raios-X e microscopia de varrimento de electrões; ambas as fases, ferroelectrica e ferromagnética apresentam distorções apreciáveis dos ...

Growth of complex single-crystal hexagonal ferrites

Materials Research Bulletin, 1967
Abstract Numerous “mixed-layer type” hexagonal ferrites have been grown as crystals from molten flux. Two structural series both of which belong to ternary systems of the type BaO-MeO-Fe 2 O 3 are differentiated. In the structural series M n Y p , Me was Zn, Mg, Ni, Co, Fe, Cu, and Mn.

Structure of hexagonal copper(I) ferrite

Acta Crystallographica Section C Crystal Structure Communications, 1991
CuFeO 2 cristallise dans P6 3 /mmc avec a=3.035, c=11.449A, Z=2; affinement jusqu'a R=0.033. Les octaedres d'aretes communes forment des couches de type brucite, liees par des atomes de cuivre coordines de facon lineaire. C'est un polytype du delafossite (3R-CuFeO 2 )

Moulding of sintered hexagonal ferrite material

1995
The invention relates to a moulding of a sintered hexagonal ferrite material. This moulding is characterized in that the majority of the grains of the material have a monodomain structure. By virtue thereof, the loss factor tan delta of this material is much smaller than that of corresponding known materials if said material is used in the frequency ...
