Plasma Etching‐Assisted Perpendicular Magnetic Anisotropy
physica status solidi (a), 2021Ferromagnetism with perpendicular magnetic anisotropy (PMA) receives continuous attention. But, the PMA is always limited by materials system, the assistance from suitable buffer layers such as Pt and Ta is essential. A general method for the generation of PMA on various systems is pursued.

Perpendicular magnetic anisotropy for CoFeBZr/MgO
2015 IEEE Magnetics Conference (INTERMAG), 2015Magnetic tunnel junctions (MTJs) using perpendicular magnetic anisotropy (PMA) have been studied for high density magnetoresistive random access memory (MRAM) with the expectations of scalability for driving current and reducing switching anomalies by local magnetization non-uniformity.

Magnetic logic using nanowires with perpendicular anisotropy
Nanotechnology, 2009In addition to a storage function through the magnetization of nanowires, domain wall propagation can be used to trigger magnetic logic functions. Here, we present a new way to realize a pure magnetic logic operation by using magnetic nanowires with perpendicular anisotropy.

Magnetization reversal in nanoscale magnetic films with perpendicular anisotropy
Physical Review B, 1994We present experimental results on magnetization reversal for a class of nanoscale magnetic films with perpendicular magnetic anistropy and develop a model that describes a variety of related experiments. In this model the sample is divided into identical single domain cells that interact through dipolar fields and a nearest-neighbor domain-wall ...

Magnetoresistive sensors with perpendicular magnetic anisotropy
Journal of Applied Physics, 2005A magnetoresistive (MR) read sensor design for magnetic recording has been proposed in an attempt to solve the magnetization distribution and thermal stability problems of nanometer-scale read sensors. In this design, the free layer has a perpendicular-to-plane easy axis and the reference layer has an in-plane easy axis. The giant-magnetoresistive film

Perpendicular Magnetic Anisotropy of TbCo Films
Japanese Journal of Applied Physics, 1984An experimental study has been made on the magnetic anisotropy of amorphous TbCo films prepared by rf co-sputtering. TbCo films prepared at a substrate bias voltage of –100 V exhibit a large uniaxial anisotropy of 2×106 erg/cm3 with its easy axis perpendicular to the film plane, whereas films prepared without the substrate bias exhibit the ...

Perpendicular anisotropy in magnetic multilayer films
Journal of Magnetism and Magnetic Materials, 1992Abstract A single-ion model approximated by point charge interaction is proposed to account for the perpendicular anisotropy K u in Tb/Fe, Pt/Co multilayer films. For the former, a quasi-self-consistent method of determining the crystal field coefficient D and the average orientation of the moments in the interface is developed during the ...

Perpendicular magnetic anisotropy of NdFe films
Journal of Physics: Condensed Matter, 1990The perpendicular magnetic properties of NdFe alloy thin films have been studied on samples prepared by the facing targets sputtering method at a substrate temperature of 240-270 degrees C. All the films with Nd content over 35 at.% exhibit perpendicular magnetic anisotropy.
