In this work, the effects of Cr on the microstructure, physical, and AC magnetic properties of the Ni49Fe51 alloy was studied. In this respect, three series of thin sheets of (Ni49Fe51)(100-x)Cr-x (x = 0, 3, and 7 at. pct) alloys with a final thickness of 120 mu m were prepared by means of severe cold rolling and an 1150 degrees C annealing process at H-2 atmosphere. Optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD), (200) X-ray pole figure, and magnetic force microscopy (MFM) were employed to study microstructure, texture, and magnetic domain structure of the alloys. The magnetic characteristics of the samples were evaluated using BH-hysteresis loop tracer at a frequency range of 0.5 to 300 Hz. Based on the results obtained, it was shown that the mean magnetic domain width was increased from 1.006 to 1.398 mu m for 0 Cr and 7 Cr samples, respectively. Furthermore, the magnitude of the static hysteresis loss increased and the excess and classical eddy current loss decreased for the Cr-added thin sheets.
