| Abstract: | The effect of pressure on the electrical resistance of Fe90Zr10 and (Fe0.96Ni0.04)90Zr10 amorphous alloys has been investigated. The minimum point in the electrical resistance versus temperature curve shifts toward lower temperature range with increasing hydrostatic pressure, corresponding to the shift of the Curie temperature. The decrement of the electrical resistance below the Curie temperature Tc is about twice that above Tc, suggesting a large compressibility in the ferromagnetic state of the amorphous Invar alloys. |
