A body centred tetragonal phase (Fe, Ni), (P, B) is formed during the crystallization process of an amorphous alloy with the composition of FemNimP14B6. I n the electron diffraction patterns of this compound streaks parallel to the (001)* reciprocal plane are found passing through all diffraction spots with odd indices of 1. This can be satisfactorily explained by the presence of numerous micro one-dimensional inversion domains in the [OOl] direction.Eine raumzentrierte tetragonale Phase (Fe, Ni), (P, B) wird wiihrend des Kristallisationsprozesses einer amorphen Legierung mit der Zusammensetzung Fe,Ni,P,,B, gebildet. I n den Klektronenbeugungsdiagrammen dieser Verbindung werden Streifen parallel zur reziproken (001) *-Ebene beobachtet, die durch alle Beugungspunkte mit ungeraden Indizes von 1 gehen. Dies lLBt sich durch das Vorhandensein von zahlreichen eindimensionalen Mikro-Inversionsdomiinen in der [001]-Richtung erkliiren.

The influence of isothermal crystallization on the coercive field of the amorphous alloy Fe40Ni40P14B6 is investigated by combining magnetic measurements and transmission electron microscopy (TEM) observations. It is found, that the statistically distributed crystalline regions with barrel like shape and diameters up to some micrometers act as pinning centres for domain walls. In the early stage of crystallization the coercive field is mainly determined by the pinning of the domain walls in the amorphous phase at statistically distributed crystallites. With increasing degree of crystallization the coercive field of the alloy is determined by the coercive fields of the different crystalline phases.
