Abstract: Structure and magnetic properties of nickel oxide (NiO) nanopowders have been studied by X-ray/neutron diffraction, SQUID magnetometer, and micro-Raman spectroscopy. Our diffraction data indicate that at room temperature all NiO powders are antiferromagnetically ordered and have a rhombohedral (R-3m) phase. The SQUID magnetometry and Raman spectroscopy measurements support the presence of the antiferromagnetic ordering.

Abstract: Magnetic, electronic, structural and magnetovolume properties of the R2Fe17-xMx (R = Y, Lu, Ce; M = Si or Al) compounds were studied. We pioneered to apply electronic band parameters determination to account for the anomalous volume dependence of ferromagnetism in these compounds.
