The invention concerns a method for fabricating an array of magnets (10), the method comprising: - a step of deposition of a coercivity changing element according to a pattern on a first material having a first coercivity value, the coercivity changing element being adapted to change the coercivity of the first material, and - a step of diffusion of the coercivity changing element into certain regions to form a magnetic layer (16) having first areas (A1) made of the first material and second areas (A2) having a second coercivity, made of a second material comprising the first material and the coercivity changing element.

Spin-Hall nano-antenna (SHNA) devices are disclosed which leverage the inverse spin Hall effect and spin pumping to receive electromagnetic signals and convert them to electrical signals. Transmitter functionality is also enabled by exemplary SHNA devices. Some disclosed antennas are compatible with acoustic antenna functionalities but may also be configured to not include any acoustic functionalities. Omission of acoustic functionality requirements allows some embodiments to be fabricated on silicon wafers and hence become compatible with mainstream silicon technology. Directionality (radiation or reception patterns) of respective SHNA devices may be determined by use of different anisotropic shapes / geometries. Multiple SHNA can be fabricated on the same chip and made to radiate with different intensities in different directions for multiple-input-multiple-output (MIMO) functionality.
