Researchers have developed a novel magnetic tunnel junction (MTJ) that functions as a signed spiking neuron, capable of carrying richer information than standard spiking neurons. This compact device utilizes orthogonal easy axes in its magnetic layers to generate bipolar spikes and accurately model signed leaky integrate-and-fire (LIF) dynamics. When integrated into a network, this MTJ-based neuron achieved high accuracy on image classification tasks like CIFAR-10, demonstrating its potential for efficient neuromorphic computing. AI
