The new cubic iron-nitride phase FeN prepared by reactive magnetron sputtering

Nanocrystallization and amorphization induced by reactive nitrogen sputtering in iron and permalloy

“…It is known that when heated, evaporated, ablated or sputtered in nitrogen environment or with nitrogen ion, iron forms a microstructure with a variety of FeN alloys and compounds, including the recently discovered newcubic-type nitrides. 21,26 Ferromagnetic nitrides of iron have received tremendous interests in magnetic functional devices. 31,32 On the other hand, NiFe alloy with a composition of Ni 80 Fe 20 is a well-known soft-magnetic alloy and is known as permalloy.…”

Investigation on the structure and magnetic properties at low temperature for nanocrystalline γ′-Fe4N thin films

“…It is well known that some iron nitrides such as -Fe 3 N (hcp), ␥ -Fe 4 N (fcc) and ␣ -Fe 16 N 2 (bct) are magnetic phases [13][14][15]. Among different phases of iron nitrides, the ␥ -Fe 4 N phase has the face-centered cubic iron lattice with a nitrogen atom positioned at the body-center site.…”

Structural and magnetic properties of nanocrystalline Fe–N thin films and their thermal stability

“…Since the first report on the possible 'giant-moment' ␣ -Fe 16 N 2 phase by Kim and Takahashi, ferromagnetic iron nitride compounds, such as ␣-Fe (N), -Fe 3 N (hcp), ␥ -Fe 4 N (fcc), and ␣ -Fe 16 N 2 (bct), have been intensively investigated [9][10][11][12][13][14][15][16][17]. Recently, synthesis and characterization of nanocrystalline iron nitride have been attracting widespread attention because of their unique magnetic properties and the improved performances determined by their particle sizes, surface structures and inter-particle interaction [18][19][20][21][22][23][24][25].…”
