| 英文摘要 | Two channels of the conductance g exist in cold-pressed powder compacts of cro2/(cro2/cr2o3), where two types of granules have different coercivities. one of the channels is the spin-dependent intergranular tunneling conductance, and the other one is the spin-independent higher-order inelastic hopping conductance. the conductance is mainly related with the spin-dependent tunneling channel at low temperature. a large low field tunneling magnetoresistance (tmr) of 30.4% is achieved in 950 oe field at 2 k. the reason is the relative orientation of the magnetization that tends to be antiparallel between the two coercivities. field dependence of the tunneling magnetoresistance shows two better-separated peaks than that of cro2 powder compact. the results suggest that the introduction of cro2/cr2o3 improves low field sensitivity, tmr, and switching characteristics.
