本文叙述金属与合金的各向导性的磁电阻效应，磁性金属／金属多层膜的巨磁阻效应。恒流电镀制备巨磁阻金属多层膜以及巨磁阻金属多层膜应用。在室温条件下，用含有Co2＋、Ni2＋、Cu2＋离子的化合物作电解质，恒流电镀。具有巨磁阻效应的Cu－Co－Ni／Cu多层膜生长在抛光的铜基质上，在室温条件下，磁场强度为0～1T，测得电磁阻变化率达到2．45％。

The paper describes the anisotropic usual magnetoresistive effect of metal and alloy and the gian magnetoresistive effect of magnetic metal/metal multilayers.Giant magnetoresistance of metal multilayers grown by galvanostatic electrodesposition were widely applied.At room temperature, galvanostatic electrodeposition was performed from an electrolyte containing Co2+, Ni2+, Cu2+ ions. Multilayers were electrochemically deposited on the polished copper substrate.At ambient temperature, magnetic fields from O to 1 T were applied. The CMR ratio of 2.45% was obtained.
