Abstract
The invention relates to a method for producing a device comprising magnetic blocks magnetized in different directions, comprising steps of: a) forming, in a stack of one or more layers of at least one antiferromagnetic material and one or more layers of at least one ferromagnetic material resting on a substrate, at least one first block and at least one second block, said blocks being longilineal and separate and extending respectively in a first main direction and in a second main direction, the first and the second main direction forming between them a first non-zero angle α, b) annealing said blocks at a temperature greater than the ordering temperature of said antiferromagnetic material or than the blocking temperature or than the Néel temperature of said antiferromagnetic material.
