A new type of microcombs (microstructures with alternating magnetization zones) based on microwires in which the magnetization periodicity is caused by equidistant alternation of natural domains is proposed. The presence of quasi-periodic radial magnetization and the effect of temperature and magnetic field on the magnetic relief in PrDy-FeCo-B microwires are established. Analysis of the chemical, phase and structural composition of the microwires revealed the necessary conditions for creating a periodic magnetic relief. It is established that annealing affects the magnetic relief and changes the structure of initially amorphous microwires. Keywords: microstructures, amorphous, rare earth, radial domains, magnetic domain structure, microcombs.
