| 1 | STRUCTURE AND MAGNETIC PROPERTIES OF YFe_(12-x)Ti_x COMPOUNDS显示文摘Structure and magnetic properties of the YFe12-x Tix compounds with x=0.85, 1.00, 1.10, 1.20 and 1.30 have been investigated. Both the thermomagnetic analysis and X-ray diffraction patterns show that all compounds Btudied are almost single phase and crystallize in the ThMn12-type of structure. The lattice parameters a, c and unit cell volume V increase monotonously with increasing Ti content. Curie temperature Tc is almost independent on Ti content while the spontaneous magnetization Mo, the anisotropy field B. and the anisotropy constant K1 decrease monotonously with increasing Ti content and increasing temperature from1.5K to 293K. | B.

| 2 | Magnetic properties of Fe_(3(1-x))Cr_(3x)C alloys显示文摘The magnetic properties of Fe3(1-x)Cr3xC alloys with x=0.05, 0.1, 0.15, and 0.2, which crystallize in the cementite Fe3C-type structure with space group Pnma, were investigated by means of magnetization measurements. These alloys show temperature-induced second-order magnetic phase transitions. The Curie temperature (Tc) of these alloys decreases with increasing x. The isothermal magnetic-entropy changes of these alloys were derived from the magnetic isotherms measured with increasing tem-perature and increasing field. The maximum values of the magnetic-entropy change are about 0.9 and 3.6 J·kg-1·K-1 at Tc =360 K for x = 0.05 in a magnetic field change from 0 to 1 T and 0 to 5 T, respectively. | Feng-qi Zhao O.
