MATERIAL LAYER FOR AN ELECTRIC MACHINE, STACK OF MATERIAL LAYERS, AND METHOD

The invention relates to a material layer for an electric machine, the material layer (2) having a first layer (4), which in the direction of extension of a plane has a first material (6), to which a second material (8) adjoins in the direction of extension of the plane, the two materials (6, 8) being bonded to each other along a first connecting section (10), the first material (6) has a lower magnetic permeability value [mu] [tau] relative to the second material (8), characterized in that the material layer (2) has a second layer (12), which is bonded to the first layer (4) and at least partially covers the first layer on a planar side (14), the first layer comprises at least two materials, and the second layer likewise comprises at least two materials, namely a third material (16) and a fourth material (18), which are further connected along a plane extension along a second connection section (20), the region of the third material (16) or the region of the fourth material (18) at least partially overlappin
