Hard Magnetic Thin Films

Hard magnetic films have a broad application area ranging from magnetic recording media to microelectromagnetic devices. A challenge for recording media is the 60% annual increase in areal density, which requires ever smaller magnetic dots. However, for a given magnetic anisotropy the reduction of dot size is limited, since below a critical magnetic volume the magnetisation becomes thermally un...

HITPERM soft-magnetic underlayers for perpendicular thin film media

A class of nanocrystalline alloys, HITPERM ~Fe, Co!–M–B–Cu (M5Zr,Hf,Nb, etc.! found to exhibit excellent soft-magnetic properties is being studied for use as a soft-magnetic underlayer for perpendicular recording media. Previously, we reported that HITPERM films of ;100 nm thickness sputtered at room temperature ~RT! and at ;2.3 W/cm power density had exhibited an amorphous microstructure, whic...

Thin Film Media II M. Russak, Chairman FeAl underlayers for CoCrPt thin film longitudinal media

B2 ordered FeAl films with a small, uniform grain size have been produced by rf diode sputter deposition on glass substrates. CoCrPt films grown on FeAl underlayers were found to have the ~101̄0! lamellar texture. The in-plane coercivities (Hc) of the CoCrPt/FeAl films are comparable to those of the CoCrPt/Cr films and they can be further improved by inserting a thin Cr intermediate layer betwee...

Scattering of Elastic Waves by Inclusions with Thin Interface Layers

Elastic waves are scattered by an elastic inclusion. The interface between the inclusion and the surrounding material is imperfect: the discontinuity in the displacement (traction) vector across the interface is taken to be proportional to the average of the traction (displacement) vectors on the two sides of the interface. Uniqueness theorems are obtained, and boundary integral equations over ...
