Major and minor magnetostriction hysteresis loops of Co–Cu–Ni ferrite

Abstract Initial curve, major and minor magnetostriction hysteresis loops (butterfly loops) as the functions of the static magnetic field of the Co 0.004 Cu 0.12 Ni 0.866 Fe 2.01 O 4.02 ferrite were investigated. The saturation magnetostriction for the field equal to 2500 A/m was negative and equal to −11.1×10 −6 and for the field of 540 A/m (equal to 3 H c ) was equal to −8.0×10 −6 . Other minor magnetostriction hysteresis loops are presented.
