DC-magnetron sputtering was employed to prepare Fe-N/Ti-N periodic nano-multilayers . Magnetic properties were studied by vibrating sample magnetometry and structure by TEM and X-ray diffraction for the films. A strong enhancement of the saturation magnetization was found in multilayers containing thinner Fe-N layers. The coercivity was found to be nearly constant. A kind of anomalous hysteresis loops was found in some samples
