The lattice constants of Hf1-xTaxFe2 with C14 structure were measured at room temperature under pressure up to 5 GPa. The magnetic phase diagram obtained as a function of pressure was compared with that obtained as a function of Ta concentration x. It is shown that changes in lattice ...
Transverse and longitudinal magnetostriction and magnetization processes were measured for a Laves phase compound of Hf1-xTaxFe2 polycrystal using pulsed high magnetic fields up to 440 kOe. Magnetic phase boundaries were determined for x=0.25 and 0.3. An isotropic forced magnetostriction was observed ...
Magnetoelastic and pressure effects at the antiferro–ferromagnetic transition in Hf1-xTaxFe2-y alloys.Presents a study which measured the magnetoelastic and pressure effects at the antiferro-ferromagnetic transition in Hf[sub1] - [subx]Ta[subx]Fe[sub2] - [suby] alloys. Linear thermal ...
Changes in the magnetic properties of the intermetallic compound Hf1xTaxFe2 upon high-energy ball milling are investigated by Mssbauer spectroscopy. X-ray diffraction and magnetization measurements suggested that a little disorder generated by ball milling significantly affected the magnetic properties in ...

We have measured the magnetization and Mssbauer effect on amorphous Hf 1 xTa xFe 2 alloys prepared by sputtering from 4.2 to 300 K. The alloys are found to be an itinerant electron ferromagnet with a wide distribution of the local Fe moment. The ferromagnetic moment decreases with increasing ...
The intermetallic compounds Hf 1 XTa XFe 2 show a first-order magnetic transition (FOMT) from a ferromagnetic (F) to an antiferromagnetic (AF) state with increasing temperature. The magnetization decreases abruptly at the phase transition temperature. We report the magnetic entropy change of these...
Pressure effectThe effect of hydrostatic pressure on the magnetic properties has been investigated for itinerant-electron metamagnetic Hf1xTaxFe2 (x=0.125 and 0.14) compounds which exhibit a temperature-induced transition from the ferromagnetic (FM) to the antiferromagnetic (AFM) state upon heating. ...
