A magnetic alloy is a combination of various metals from the periodic table such as ferrite that exhibits magnetic properties such as ferromagnetism.
Typically the alloy contains one of the three main magnetic elements (which appear on the Bethe-Slater curve): iron (Fe), nickel (Ni), or cobalt (Co).
[1] Magnetic properties of an alloy are highly dependent not only on the composition but also on heat treatment and mechanical processing.
[2][3] Samarium–cobalt magnets are made from an alloy of samarium and cobalt, known for their high magnetic strength, excellent temperature stability and resistance to demagnetization.
[4] They are often used in applications requiring powerful and stable magnets, such as in motors, aerospace, military equipment, and high-temperature environments.
