Spin Transfer Induced Magnetization Switching in CoGd|Cu|CoFe Spin Valves

Current-induced-magnetization-switching (CIMS) has engendered considerable interest in recent years due to its potential for spintronic applications, for example, for the writing of memory cells in magnetic random access memory (MRAM). To date, most work has focused on the CIMS effect in spin valves or tunnel junctions with ferromagnetic electrodes. In this paper, the authors report a CIMS effect in spin valves with ferrimagnetic Co-Gd electrodes.
