“…In recent years, though, there has been a growing interest in replacing FM with materials with negative exchange coupling, such as ferrimagnets and antiferromagnets. In particular, RE–TM ferrimagnetic alloys have been proven to be ideal candidates because of their versatility to vary their magnetization with composition, and because they exhibit PMA even in bulk form due to different reasons [ 68 , 69 , 70 , 71 ]. This is the case especially near T comp , because of the reduced magnetostatic energy associated with a small magnetization due to the partial (or total) cancellation of the moments of the two sublattices that form the material.…”

Ferrimagnetic thin films formerly played a very important role in the development of information storage technology. Now they are again at the forefront of the rising field of spintronics. From new, more efficient magnetic recording media and sensors based on spin valves to the promising technologies envisaged by all-optical switching, ferrimagnets offer singular properties that deserve to be studies both from the point of view of fundamental physics and for applications. In this review, we will focus on ferrimagnetic thin films based on the combination of rare earths (RE) and transition metals (TM).

“…Первыми РЗМ/ПМ сверхрешетками, в которых ПМА наблюдалась для сравнительно толстых слоев (до 18 ¦ ), были системы Co/Dy [1][2][3]. Недавно нами было показано, ПМА в сверхрешетках Co/Dy может наблюдаться и при более толстых слоях Co и Dy (до 30 ¦ ) в зависимости от микроструктуры образцов [4]. В настоящей работе мы сообщаем об исследовании влияния кристаллической структуры на магнитную анизотропию и магнитное упорядочение сверхрешеток Co/Dy с различными толщинами слоев Co.…”

The influence of structural properties on the formation of perpendicular magnetic anisotropy in Co/Dy superlattices is investigated. It is established that superlattices are a compositionally modulated alloy in which, on the one hand, a strict periodicity is maintained in the thickness and composition of the layers, and on the other hand, the interdiffusion of Co and Dy at the interlayer boundaries leads to a periodic change with the depth of the concentration of Co and Dy. It is shown that the perpendicular magnetic anisotropy in Co/Dy is due to the perpendicular orientation of the magnetization in the alloying CoDy layers, while the magnetization of the Co layers is oriented in the sample plane.
