The Effects of Transverse Stress on Magnetization.
Abstract
The effects of transverse stress on the magnetization of 3NiCr steel were derived and observed in terms of three separate contributions. First, the previously determined stress-effective field was examined for transverse stress, and agreed with the results obtained in past experiments. A reversal of the effects of tension and compression was predicted and observed. Second, the stress-sensitive reluctance was found to behave linearly with tensile strain. The experimentally observed slope of 1.55 + or - .05 correlated with the derived value of 1.60 + or - .06. A lower limit to the reluctance was seen in compression. The third effect was the fractional populations of stress-active domain walls. This is a newly postulated effect which accounts for large-scale changes in domain structure due to the application of external stress. The fractional populations of field-enhancing domain walls was observed to be equal to that of filed-reducing walls. Furthermore, the total population of stress-active walls was found to be a function of applied stress.
