Magnetic properties of Fe1−xZrx in ball milling process
Journal of Magnetism and Magnetic Materials, 1995Abstract Structural features and magnetic properties of Fe 1− x Zr x upon ball milling were investigated by X-ray diffraction, magnetization measurements and Mossbauer spectroscopy. The X-ray diffraction patterns of the milled Fe 0.9 Zr 0.1 did not clearly show a sign of existence of an amorphous phase.
