“…In this case MR(H) dependences obtained for the composites and pure nickel should be similar. However, pure nickel exhibits anisotropic magnetoresistance (AMR) [10], while in Ni 27 (MgO) 73 and Ni 29 (MgO) 71 samples the effect is isotropic. This feature may be related to the fact that the Т С value of these samples is near 298 K. In such a case the main contribution to their magnetization is made by the paraprocess which causes a decrease of the samples resistance over the whole range of the magnetic fields.…”

Magnetoresistive effect and electrotransport properties of Niх(MgO)100-х (x: 21-48 at.%) granular composites have been investigated. It is found that prepercolated composites (x < 24 at.%) do not exhibit magnetoresistive properties. After percolation threshold (x: 27-29 at.%) the composites exhibit isotropic negative magnetoresistance (-0,2 %) which has not tunneling nature. Also weak localization is realized in these samples at temperatures below 100 K. At high metal concentration (32 at.% < x) the composites exhibit anisotropic magnetoresistance.

“…On the basis of relation (1), which was found experimentally [6], and relation (2), following from the thermodynamic theory of second order phase transformations [9_], equations (5) omd (6) wore found, describing the isotherms of the magneto-resistance change in the region of the Curie point. The relations obtained are in good agreement with the experimental rosults for electrolytic nickel (Figs.…”
