X-ray Images Bring Magnetic Effects Into Focus (IMAGE)
Caption
In these rows of sequenced images, produced using X-ray-based techniques, the first column shows the demagnetized state of a multilayer material containing gadolinium and cobalt; the second column shows the residual magnetism in the same samples after an external, positive magnetic field was applied and then removed; and the last column shows the samples when a negative magnetic field is applied. The white arrows in the third row of images indicate gadolinium-rich regions in the material. Click the image to view at a larger size.
