The paper describes the experimental and numerical investigations of micromagnets designed for inhomogeneous field generation in silicon qubits based on Si/SiGe heterostructures with quantum dots formed by electric gates. Measurements were performed by the optical magnetometry and magnetic force microscopy methods. It is shown that the given micromagnet geometry ensures magnetic field gradients required to induce the electric dipole spin resonance in one or more quantum dots and is suitable to control qubit states based on quantum dots. Keywords: micromagnets, quantum dots, qubits, cobalt films.
