Modifies a noun

• layer: The ferromagnetic layers introduce the spin assymetry needed to make use of the electron's spin.

• metal: In order to inject and detect spins from a ferromagnetic metal into a semiconductor, the resistivity mismatch problem has to be overcome.

• material: Does the device contain any chrome, steel, ferromagnetic materials or alloys?

• object: Implanted ferromagnetic objects can pose a serious safety problem.

• semiconductor: We will study these phenomena in both conventional magnetic metals and ferromagnetic semiconductors.

• phase: Ferromagnetic phases of the manganites can be used as a source of highly spin polarized electrons, e.g. for spin electronics and quantum computing.
