Strong toroidal magnetic fields can be generated by differential rotation induced by r-modes in the core of the rapidly rotating neutron stars (NSs). The intensities of these fields can reach strengths of order 1014 G deforming significantly the star. The magnetically deformed NS may radiate gravitational waves (GWs) if the symmetry axis of the generated magnetic field is not aligned with the spin axis. This mechanism may explain the upper limit of the spin frequencies of accreting NSs in Low Mass X-ray Binaries (LMXBs).
