Phys. Rev. 38, 828 (1931) - Magnetic Properties of Copper

1931-8-15  X-ray photographs of the alloys show that they are a homogeneous mixture of the copper and nickel crystals. Although copper is only weakly diamagnetic it requires 0.8 or 0.9 percent nickel to neutralize this diamagnetic effect and 56 percent nickel is required before the alloy shows ferromagnetic properties at ordinary temperatures.

Is Nickel Magnetic? - Techiescientist

2022-5-5  Nickel (Ni) is ferromagnetic in nature, because of the parallel alignment of its 2 unpaired electrons or ‘spins’ in presence of an external magnetic field. Nickel holds its magnetic property even in absence of any magnetic field, which gives permanent magnetization to it. Nickel exists as a silvery-white lustrous metal with a tinge of gold.

EFFECT OF IRRADIATION ON NICKEL AND IRON--NICKEL

Iron alloys containing copper and nickel were irradiated at 288 C to a fluence of 4.63 {times} 10{sup 19} neutrons/cm{sup 2}. Neutron irradiation produced defects which were observable by TEM in all of the iron alloys studied. The TEM analysis of the defects showed them to be interstitial dislocation loops with a and a/2 Burgers vectors.
