2. Effect of substrate temperature and deposition rate on alloyzation for Co or Fe onto Cu(001) substrate

Author

Zheng-Han Hong, Shun-Fa Hwang, and Te-Hua Fang

Subjects
Coating processes -- Analysis, Cobalt -- Thermal properties, Copper alloys -- Thermal properties, Copper alloys -- Mechanical properties, Iron -- Thermal properties, Molecular dynamics -- Analysis, Physics
Abstract

The mixing situation of Fe and Co atoms implanting onto Cu(001) substrate is examined with regard to substrate temperature and deposition rate by using molecular dynamics. The results have shown that the morphology of the layer is under epitaxial growth as the substrate temperature is 700 or 1000K, while it is not epitaxial at the substrate temperature of 300 or 450 K.

3. Ruthenium nano-oxide layer in CoFe-Ru-CoFe trilayer system: an x-ray reflectivity study

Author

Asgharizadeh, S., Sutton, M., Altounian, Z., Mao, M., and Lee, C.L.

Subjects
Ruthenium -- Electric properties, Ruthenium -- Thermal properties, Cobalt -- Electric properties, Cobalt -- Thermal properties, Iron -- Electric properties, Iron -- Thermal properties, Physics
Abstract

The grazing incidence x-ray reflectivity technique is employed to study the electron density profiles and other characteristics of the ruthenium (Ru) nano-oxide layer present in the CoFe-Ru-CoFe trilayer system. The Ru layer is shown to confirm the thermal stability of the spacer layer after annealing.

4. A transition of interlayer coupling from antiferromagnetic to ferromagnetic observed at low temperature in CoFe/Bi/Co trilayers

Author

Jen-Hwa Hsu, Zhi-Long Xue, and Sahu, D.

Subjects
Cobalt -- Chemical properties, Cobalt -- Thermal properties, Bismuth -- Chemical properties, Bismuth -- Thermal properties, Iron -- Chemical properties, Iron -- Thermal properties, Ferromagnetism -- Research, Physics
Abstract

The temperature variation of interlayer coupling on the sandwiches with semimetal bismuth as spacer and the thermal behavior of the coupling between two ferromagnetic layers are studied. The oscillation of interlayer coupling is disappeared due to the transition from the antiferromagnetic to ferromagnetic coupling.

5. Brief rapid thermal treatment effect on patterned CoFeB-based magnetic tunneling junctions

Author

Subjects

Abstract

The brief thermal treatment effects on the magnetoresistance of microstructured [Co.sub.60][Fe.sub.20][B.sub.20]-based magnetic tunneling junctions are analyzed. The survival of magnetoresistance at higher annealing temperature is because of boron conservation in the amorphous CoFeB ferromagnetic layer at higher annealing temperature for only a short time.

6. Crystal and magnetic structures and their temperature dependence of [Co.sub.2]Z-type hexaferrite [(Ba, Sr).sub.3][Co.sub.2][Fe.sub.24][O.sub.41] by high-temperature neutron diffraction

Author

Abstract

The nonoriented and magnetically oriented specimens of [Co.sub.2]Z-type Ba ferrite [Ba.sub.3][Co.sub.2][Fe.sub.24][O.sub.41] ([Ba.sub.3]Z) and those with [Sr.sup.2+] substitution for [Ba.sup.2+] are prepared with the conventional solid-state reaction method. The change in the moment direction caused by temperature rise is attributed to the disappearance of effective moments of cobalt ions in the temperature regions of 523 to 573 K.
