ZnO/SnO2 nanotubes are prepared by electrospinning method with postannealing in air at 500 degrees C. Field emission scanning electron microscopy (FE-SEM) reveals the formation of porous ZnO/SnO2 nanotubes. The X-ray diffraction (XRD) and Raman spect

Mossbauer spectra of (La1-xSnx)(2)(Mn0.985Fe0.015)(2)O-y (x = 0.2, 0.3, 0.4 and 0.5) from room temperature to 4.2 K have been studied; in addition X-ray diffraction patterns at room temperature have been obtained. The results show that the phase comp

The magnetic properties and phase components of rapidly quenched Fe77.5Nd4B18.5 alloy as a function of quenching rate and heat treatment were studied. X-ray diffraction and thermomagnetic measurements show that the Fe77.5Nd4B18.5 ingot consists of Nd

In previous work it was discovered that the 2:17‐type rare‐earth–iron compounds with high carbon concentration could be formed by the substitution of Ga, Si, or Al, etc., for Fe in R2Fe17Cx. The effect of Al substitution for Fe on the structure

The B‐content dependence of magnetization, Curie temperature, and crystallization temperature for amorphous (Fe1−xBx)100−yNdy alloys with y=4, 7, and 12 were studied. Spontaneous magnetization shows a monotonic decrease with x, and the noncolli

In the present work we suggest a method to calculate the crystalline anisotropy constants from a hardmagnetic material with polycrystalline structure taking account of effects of the misalignment of grains and effective total demagnetization factor.
