Abstract
We apply symmetry considerations to study the possible superconducting order parameters in ferromagnetic We predict that the presence and the location of the superconducting gap nodes depend on the direction of magnetization In particular, if is directed along the z axis, then the order parameter should always have zeros. We also discuss how to determine the gap symmetry in using ultrasound attenuation measurements.
