Аннотация: Studying the properties of ferromagnetic films helps in solving the fundamental problems of the physics of magnetic phenomena and in developing the theory of ferromagnetism. Modern software and hardware, along with reliable diagnostic methods are used to research and design thin-film devices. In this regard, the development of devices and methods for measuring the magnetic characteristics of thin ferromagnetic films is an essential task. The aim of the work is to develop an unit for local measurements of the magnetic characteristics of thin ferromagnetic films, which has the ability to change the degree of locality of measurements over a wide range and has high sensitivity at the same time. The article reviews a new unit for measuring the magnetic characteristics of thin ferromagnetic films. The unit allows measuring the value and direction of the anisotropy field on a local area of the film. A block diagram and description of a new unit, as well as methods of measurements are shown in the article. The experimentally obtained distribution of the anisotropy field over the area of the studied sample of Ni -{80} Fe-{20} film is shown in this work. The experimental results confirm the compliance of the new unit with the declared characteristics. The unit can be used for non-destructive quality control and for measuring uniformity of thin ferromagnetic films magnetic characteristics. © 2020 IEEE.
