An overview of a numerical and experimental analysis of layered AMRs is presented in Sect. 4.2. However, recently, a new material was presented by Barcza et al. [60]. They presented a layered LaFe13−x−yCoxSiy material in which the Curie
temperature changes continuously along the length. They managed to produce such a layered material by pressing several powders with different Curie temperatures on top of each other with a subsequent sintering and diffusion treatment [60]. In this manner gradients of the Curie temperature between 0.3 and 10 Kmm−1 were obtained. The general idea is to make such a material in which the Curie temperature gradient would linearly and continuously change along the length (Fig. 2.2b).
