Paramagnetic Platings
Magnetic materials fall into three main categories: paramagnetic, ferromagnetic, and diamagnetic.
When exposed to a magnetic field, a paramagnetic substance becomes magnetized, losing its magnetism when the field is removed. Ferromagnetic materials retain their magnetization even after the magnetic field is removed and can be classified into hard and soft varieties. Hard ferromagnetic materials, highly magnetized, are used for permanent magnets, while soft ferromagnetic materials, which lose or reverse magnetization easily, serve as storage media.
Mitsuya's Nickel-Iron alloy plating belongs to the soft magnetic category. Similar to invar or permalloy, its properties can be adjusted by varying the iron content. This plating is used in magnetic shielding, magnetic heads, and magnetic sensor materials applications.
