摘要： A CoFeB or CoFeNiB magnetic layer wherein the boron content is 25 to 40 atomic % and with a thickness

摘要翻译： 使用硼含量为25〜40原子％并且厚度<20埃的CoFeB或CoFeNiB磁性层来实现磁性器件中的高垂直磁各向异性和增强的热稳定性。 将Co，Ni，Fe或其合金制成的除尘层添加到CoFeB层的顶表面和底表面，以增加磁阻以及改善Hc和Hk。 另一实施例包括在CoFeB自由层中的非磁性金属插入。 具有升高的B含量的CoFeB层可以作为自由层偶极层或参考层并入STT-MRAM存储元件或包括自旋转移振荡器的自旋电子器件中。 热稳定性增加，使得在退火至至少400℃1小时后保留大量的Hk。 实现了Ku增强，并且用于STT-MRAM设计的存储单元的保留时间增加。

摘要： An improved PMA STT MTJ storage element, and a method for forming it, are described. By inserting a suitable oxide layer between the storage and cap layers, improved PMA properties are obtained, increasing the potential for a larger Eb/kT thermal factor as well as a larger MR. Another important advantage is better compatibility with high processing temperatures, potentially facilitating integration with CMOS.

摘要： A synthetic antiferromagnetic (SAF) structure for a spintronic device is disclosed and has an AP2/antiferromagnetic (AF) coupling/CoFeB configuration. The SAF structure is thinned to reduce the fringing (Ho) field while maintaining high coercivity. The AP2 reference layer has intrinsic perpendicular magnetic anisotropy (PMA) and induces PMA in a thin CoFeB layer through AF coupling. In one embodiment, AF coupling is improved by inserting a Co dusting layer on top and bottom surfaces of a Ru AF coupling layer. When AP2 is (Co/Ni)4, and CoFeB thickness is 7.5 Angstroms, Ho is reduced to 125 Oe, Hc is 1000 Oe, and a balanced saturation magnetization-thickness product (Mst)=0.99 is achieved. The SAF structure may also be represented as FL2/AF coupling/CoFeB where FL2 is a ferromagnetic layer with intrinsic PMA.

摘要： A magnetic element in a spintronic device or serving as a propagation medium in a domain wall motion device is disclosed wherein first and second interfaces of a free layer with a perpendicular Hk enhancing layer and tunnel barrier, respectively, produce enhanced surface perpendicular anisotropy to increase thermal stability in a magnetic tunnel junction. The free layer may be a single layer or a composite and is comprised of a glassing agent that has a first concentration in a middle portion thereof and a second concentration less than the first concentration in regions near first and second interfaces. A CoFeB free layer selectively crystallizes along first and second interfaces but maintains an amorphous character in a middle region containing a glass agent providing the annealing temperature is less than the crystallization temperature of the middle region.

摘要： A magnetic element is disclosed wherein first and second interfaces of a free layer with a perpendicular Hk enhancing layer and tunnel barrier, respectively, produce enhanced surface perpendicular anisotropy to increase thermal stability in a magnetic tunnel junction (MTJ). The free layer may be a single layer or a composite and is comprised of one or more glassing agents that have a first concentration in a middle portion thereof and a second concentration less than the first concentration in regions near first and second interfaces. As a result, a CoFeB free layer, for example, selectively crystallizes along first and second interfaces but maintains an amorphous character in a middle region containing a glass agent providing the annealing temperature is less than the crystallization temperature of the middle region. The magnetic element may be part of a spintronic device or serve as a propagation medium in a domain wall motion device.
