| Mössbauer spectroscopy of 57Fe and X-ray diffraction measurements in the Zr1-xTixFe2 phase have been made. Our X-ray diffraction spectra revealed that the samples have the cubic C15 crystal structure for low Ti concentration and the hexagonal C14 structure for high Ti concentration. In the range of 0.2<= x <= 0.5 a mixture of both structures occurs. The investigated compounds are paramagnetic at RT for x>0.80 and magnetic for x<=0.8. In the magnetic samples we found four different values of hyperfine magnetic fields. The presence of two hyperfine magnetic fields in the C14 phase suggests magnetic moments on Fe atoms at 2a sites. The obtained ϵQ vs. the x dependence indicates the spin canted antiferromagnetic structure in the hexagonal phase in the range of 0.2<= x <=0.8. |
