【 摘 要 】

The effect of Zr addition and microstructure refinement on the local magnetic properties of intermetallic compound Nd2Fe14B in micro- and nano-crystalline alloys was studied by X-ray Magnetic Circular Dichroism. XMCD spectra were measured at the beamline ID-12 of ESRF (Grenoble, France) at the Fe-K and Nd-L3,2absorption edges in a magnetic field of 10 T at room temperature. The noticeable differences of XMCD amplitude signals, measured on the samples with different content of Zr and various parameters of the microstructure were found, which clearly indicates the influence of the both factors on the magnetic state of Nd and Fe ions in the Nd2Fe14B-based compounds.
