Spin transistors and related memory, memory systems, and methods are disclosed. A spin transistor is provided by at least two magnetic tunnel junctions (MTJs) with a shared multiferroic layer. The multiferroic layer is formed from a piezoelectric (PE) thin film over a ferromagnetic thin film (FM channel) with a metal electrode (metal). The ferromagnetic layer functions as the spin channel and the piezoelectric layer is used for transferring piezoelectric stress to control the spin state of the channel. The MTJ on one side of the shared layer forms a source and the MTJ on the other side is a drain for the spin transistor. |
