    "abstract": "We consider s=1/2 spins in the presence of a constant magnetic field in\nz-direction and an AC magnetic field in the x-z plane. A nonzero DC\nmagnetization component in y direction is a result of broken symmetries. A\npairwise interaction between two spins is shown to resonantly increase the\ninduced magnetization by one order of magnitude. We discuss the mechanism of\nthis enhancement, which is due to additional avoided crossings in the level\nstructure of the system.",
