In sputter‐deposited Ni1−xAlx alloys, a disordered f. c. c. phase appears for 0 ≦ x < 0.3 and 0.85 < x ≦ 1.0, the B2 type ordered phase for 0.35 < x < 0.6, a disordered b. c. c. phase for 0.6 < x < 0.65, and an amorphous phase for x = 0 to 0.15 are ferromagnetic, while the other phases are paramagnetic down to 4.2 K. The electrical resistivity at 4.2 K, ϱ(4.2), is small and the temperature coefficient of electrical resistivity, TCR, is positive for the disordered f. c. c. and ordered b. c. c. alloys, while ϱ(4.2) is very large and TCR is negative for the disordered b. c. c. and amorphous alloys.

In sputter-deposited Zr-Zn and Ni-A1 alloys, an amorphous Zr-Zn phase appears for 30-80 at % Zn, while a disordered fcc Ni-A1 phase appears for 0-30 at % A1 and an amorphous Ni-A1 phase for 65-80 at % Al. The amorphous Zr-66 at % Zn and disordered Ni-25 at % A1 alloys are paramagnetic down to 4.2 K.
