Technically all substances are magnetic in some way: it's either ferromagnetic (what most people would consider "magnetic"), paramagnetic (weakly attracted to a magnetic field), or diamagnetic (weakly repelled by a magnetic field). Not many substances are "magnetic" in the usual lay meaning of the word, though.
Supermalloy is a metal alloy that is 79% nickel, 5% molybdenum and 16% iron. It is used in mechanical and electronic components like hard drives. It is disigned to have a very high magnetic permeability and a low coercivity, meaning that magnetic fields can flow though it very easily. It is also a soft magnetic material, meaning that it doesn't stay magnetized itself once the magnetic field is removed.
