“…They exist in a relative wide homogeneity range extending for ZrFe, from about 66 to 73 atyo Fe (at 1300 to1400 "C) [l, 21 and for TiFe, from about 64.5 to 71.5 atyo Fe (at 1300 "C) [2,3]. Several investigations of the magnetic properties of ZrFe, and TiFe, are known in the literature [l, 4 to 151.…”

The magnetic properties of TiFe, and ZrFe, are investigated within their homogeneity range in dependence on the concentration. TiFe, is antiferromagnetic a t titanium excess and a t stoichiometric composition and it is ferromagnetic a t iron excess. ZrFe, is ferromagnetic throughout the whole homogeneity range. The dependences of the Curie temperatures and of the saturation magnetizations on the concentration are determined. By the present studies the discrepancies of the magnetic data of ZrFe, and TiFe, existing in the literature can be attributed to the existence of a homogeneity range Die magnetischen Eigenschaften von TiFe, und ZrFe, wurden im Homogenitiitsbereich in Abhingigkeit von der Konzentration untersucht. TiFe, ist auf der titanreichen Seite und bei stochiometrischer Zusammensetzung antiferromagnetisch, bei EisenuberschuB dagegen ferromagnetisch. ZrFe, ist im gesamten Homogenitiitsbereich ferromagnetisch. Die Abhiingigkeiten der Curietemperaturen und der Siittigungsmagnetisierungen von der Konzentration wurden bestimmt. Mit den vorliegenden Untersuchungen konnen die in der Literatur existierenden Diskrepanzen in den Angaben der magnetischen Eigenschaften von ZrFe, und TiFe, auf die Existenz eines Homogenitiitsbereiches zuriickgefiihrt werden.

Nanocrystalline Ti0.75Zr0.25Fe2+x (x = 0-0.4) and Ti0.75−yByZr0.25Fe2.4 (y = 0-0.35) with high saturation magnetization have been fabricated by the melt-spinning technique. Nanocrystalline Ti0.75Zr0.25Fe2+x consists of the hexagonal C14 Laves phase (Ti,Zr)Fe2. Fe addition decreases the lattice parameter a and shrinks the cell volume. The antiferromagnetic Fe-Fe interactions may decrease with the increase of x, leading to a significant enhancement of saturation polarization (Js) and Curie temperature (Tc). The magnetocrystalline anisotropy constant K also increases with increasing x. Excessive Fe addition (x > 0.25) may induce structural disorder which lowers the Js and Tc. Nanocrystalline Ti0.75−yByZr0.25Fe2.4 is composed of hexagonal (Ti,Zr)Fe2 and Fe-rich amorphous phases with relatively high Js. The lattice parameters a, c and cell volume V are almost unchanged with the increase of y for y ≥ 0.16. Simultaneously, the Tc of (Ti,Zr)Fe2 remains unchanged, indicating that B does not enter this lattice but takes part in forming the amorphous phase, in good agreement with the X-ray diffraction results. The volume fraction of the amorphous phase increases with the increase of B content and results in a large enhancement of Js up to 10.8 kG. Further B addition (y > 0.30) decreases Js, possibly due to the decrease of the Js of the amorphous phase.

The Laves phases ZrFe, (MgCu, type) and TiFe, (MgZn, type) have a homogeneity range of several atomic percent (mainly on the side rich in iron). An investigation is made of the modifications to this type of AB, lattice which result from an excess of B-atoms. X-ray and neutron diffraction measurements show that for both ZrFe, and TiFe, the excess B-atoms are associated with the sites of A-atoms. The concentration variation of the lattice c0nsta.nt.s confirms these results.Die Laves-Phauen ZrFe, (MgCu,-Typ) und TiFe, (MgZn,-Typ) haben einen Homogenitatsbereich ron einigen Atomprozenten, der hauptsachlich auf der eisenreichen Seite liegt. I n der vorliegenden Arbeit wurde untersucht, wie sich das AB,-Gitter bei B-Atom-Uberschuh modifiziert. Rontgenographische und neutronographische Intensitiitsmessungen ergaben, daB sowohl bei ZrFe, als auch bei TiFe, die uberschiissigen B-Atome anstelle von A-Atomen eingebaut werden. Die Abhiingigkeit der Gitterkonstanten von der Konzentration bestitigt diesen Sachverhalt.
