The loop-stage-dependent exchange bias training effect has been systematically studied in the polycrystalline FeNi/FeMn bilayers. According to the ferromagnet (FM) magnetization states, an entire magnetic hysteresis loop can be divided into four different stages: 1) positive saturation stage; 2) descending branch; 3) negative saturation stage; and 4) ascending branch. The loop-stage-dependent training...
Recently, the exchange bias (EB) phenomenon in the ferromagnet/antiferromagnet (FM/AFM) bilayer and its inborn instability effect, i.e., training effect [1], have attracted much attention for its great technological importance in spintronic devices. Usually, the study of training effect is performed by continuously recording the exchange field (HE) and the coercivity (HC) after measuring an entire...
This paper addresses the development of a new signal processing approach based on the fusion of Hilbert transform and bispectral analysis to extract features of defects in a number of induction motor conditions. The motor conditions considered are a normal motor and motors with outer, inner race and rotor faults. The signal processing techniques based on Hilbert transform have been used to extract...
In this presented work, both top and bottom pinning FeNi/FeMn bialyers were prepared by sputtering with an external field applied in the film plane during deposition. The training processes were performed with a vector vibrating sample magnetometer (VVSM) through which Mx and My can be measured simultaneously. Before the tuning process, ten loops were measured at an angle of six degrees with respect...
Three approaches based on Hilbert-based bispectral vibration analysis are investigated as vibration signal preprocessing techniques for application in the diagnosis of a number of induction motor rolling element bearing conditions. The bearing conditions considered are a normal bearing and bearings with outer and inner race faults. The vibration analysis methods investigated are based on the fusion...
