prepared by different instruments at an ultrahigh base vacuum and a lower base vacuum. The anisotropic magnetoresistance co-efficients (ΔR/R) of Ni81Fe19 (12nm) films reached 1.6% and 0.6......
. A magnetic "dead layer" could be produced in the NiFe/Ta interface. The "dead layer" is likely to influence the spinning electron transport and the magnetoresistance effect.关键词:......
were investigated after Co ion implantation and annealing at 280, 320, 360 and 400℃, respectively. GMR (giant magnetoresistance) ratio of the film with/without Co ion implantation was measured......
techniques, the sample synthesized by co-precipitation method exhibited the highest magnetoresistance (~63%).关键词:......
and magnetocaloric effect (MCE) studies of newly synthesized Gd10Co20Si70 alloy. These measurements confirm an antiferromagnetic transition at TN=9 K. Both MCE and magnetoresistance (MR) show quadratic......

GUSTAJCEV1, 2, O... that the magnetoresistance ratio attains 100 or more. The main peculiarity of the MR behavior is its strong dependence on the magnitude and the sign of the bias current across the device and, most......
and LSMO/0.33ZnO composites while the resistivity of LSMO/0.33Al2O3 decreases monotonically with increasing the temperature from 200 K to 400 K. Moreover, the temperature dependence of magnetoresistance(MR.... Key words: LSMO; magnetoresistance; two-channel model; composites; potential barrier  ......
, as an indication of the occurrence of the local Jahn-Teller effect. The measurement result of V-LCMO compounds shows that the maximum magnetoresistance(MR) is about 220% at TIM=268 K and La-vacancy content...; 1 Introduction After the giant magnetoresistance effect(GMR......
by doping leads to colossal magnetoresistance effect.The transport mechanism of metallic conduction at low temperature is mainly electron-magneton interaction and can be fitted by the formula ρ=ρ0+AT4.5......
