Atomic level mixing induced by Kr irradiation of FeCo∕Cu multilayers

Phytochrome Pelletability Induced by Irradiation in Vivo: MIXING EXPERIMENTS.

Samples of irradiated and control Avena sativa shoot tissue were homogenized together to determine whether, during homogenization phytochrome from irradiated tissue can bind to the particulate material simultaneously extracted from the control tissue. The level of phytochrome pelletability for such mixed tissue homogenizations is equal to: (a) the values obtained when the extracts from separate...

Ion irradiation induced impurity redistribution in Pt/C multilayers

Ion irradiation induced modifications of a periodic Pt/C multilayer system containing Fe impurity have been analyzed by X-ray techniques suitable for exploring nanometer depth scales with sub-nanometer depth resolution. The multilayer stack with 15 Pt/C layer pairs (period 4.23 nm, total thickness 63.45 nm) was fabricated on a glass substrate. A 2 MeV Au2þ ion beam was rastered on the sample to...

Atomic Assembly of Magnetoresistive Multilayers

Mechanisms of inert gas impact induced interlayer mixing in metal multilayers grown by sputter deposition

Control of interfacial roughness and chemical mixing is critical in nanomaterials. For example, multilayers composed of ;20 Å conductive layer sandwiched between two ;50 Å ferromagnetic layers can exhibit giant magnetoresistance ~GMR!. This property has caused a tremendous recent increase in hard disk storage capacity, and can potentially result in a new generation of nonvolatile magnetic rando...

Giant magnetoresistance in Co/Cu multilayers sputtered with Kr

The critical condition for the giant magnetoresistance (GMR) effect has not yet been fully clarified. Reports on the MR ratio of C o / C u multilayers (MLs) disagree as to whether the interfacial roughness or crystallinity of the MLs is the cause. The film morphology is significantly affected by sputtering conditions such as sputtering gas and pressure. This paper presents some results of the m...
