Permalloy is a soft ferromagnet, while FCT (face centered tetragonal) FePt is a hard ferromagnet. At the thicknesses deposited (50.0 nm permalloy, 20.0 nm FePt), the two layers couple strongly into an exchange-spring magnet.

Permalloy is the term for a nickel iron magnetic alloy. Generically, it refers to an alloy with about 20% iron and 80% nickel content. Permalloy has a high magnetic permeability, low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance.

2024年11月4日 · Permalloy, an alloy primarily composed of approximately 80% nickel and 20% iron, has become a cornerstone in the field of magnetism since its discovery in the early 20th century.

Permalloy is a general term for nickel-iron soft magnetic alloys, specifically referring to binary or multicomponent nickel-iron-based alloys that contain between 34% and 84% nickel.

Iron-nickel based soft magnetic alloys with 30-90% nickel content is collectively referred to as Permalloy. Permalloy is invented in 1914 by physicist Gustav Elmen at Bell Telephone …

2024年10月10日 · Permalloy is a nickel-iron magnetic alloy, typically composed of about 80% nickel and 20% iron. This combination gives it remarkable magnetic permeability, making it incredibly effective in applications requiring efficient magnetic shielding and minimal energy loss.

2013年8月6日 · Permalloy is known for its very high magnetic permeability, which makes it useful as a magnetic core material in electrical and electronic equipment. The other key magnetic properties it possesses are near zero magnetostriction, low coercivity, and anisotropic magnetoresistance.

The meaning of PERMALLOY is an easily magnetized and demagnetized alloy composed of about 80 percent nickel and 20 percent iron.

2019年9月23日 · Permalloy is a precision alloy of iron (Fe) (18-55 %) and Nickel (Ni) (45-82 %), which is characterized by soft magnetic properties. Permalloy can be further alloyed with several other components, for example, molybdenum (Mo), copper (Cu), chromium (Cr), silicon (Si).

The archetypal soft magnetic thin film is Ni x Fe (1-x). When x is around 0.8, the alloy is known as permalloy with the highly desirable properties of high permability, low coercivity and near zero magnetostriction. Permalloy was originally discovered by Arnold and Elmen in 1923 whilst working for Bell Laboratories [87].

Permalloy is an alloy with extremely high magnetic permeability, small coercive force, nominal core losses and small remnance by magnetic field annealing. It has applications in the magnetic shielding where fields extremely smaller than earth’s magnetism are needed.

Permalloy (Nickel 80%) or Mumetal is a magnetic shielding material that is made from a nickel-iron alloy. It has high permeability and is an ideal material for shielding in constant or low frequency magnetic regions.
