Unveiling new spin properties in artificial materials

San Sebastian, Spain (SPX) Sep 15, 2024

Researchers from Charles University in Prague and the CFM (CSIC-UPV/EHU) center in San Sebastian, in collaboration with CIC nanoGUNE's Nanodevices group, have developed a novel complex material with unique properties in the field of spintronics. This discovery, published in 'Nature Materials', opens up new avenues for creating more efficient and advanced electronic devices, including the integration of magnetic memories into processors.

The discovery of new properties in two-dimensional materials has spurred significant interest, particularly in how stacking these materials into heterostructures can create new effects. Recently, it has been observed that even slight rotations of these material layers can drastically alter their properties.

"In this work we studied the stacking of two layers of graphene and tungsten selenide (WSe2)," explained Ikerbasque Research Professor Felix Casanova, co-leader of the Nanodevices group at nanoGUNE and leader of the study. "If the two layers are placed one on top of the other and rotated at a precise angle, a spin current is generated in a desired specific direction," Casanova added.

Typically, spin (a property of electrons and other particles) is transferred perpendicular to the electric current. One of the main challenges in spintronics, a technology that uses spin to manage and transfer information, is controlling these spin currents. However, as Felix Casanova highlighted, "this work shows that this limitation in fact disappears when suitable materials are used."

He further concluded, "by simply stacking two layers and applying a 'magic' twist, new spin-related properties that do not exist in the initial materials can be obtained. The more flexibility we have in the choice of materials, the greater the design possibilities are for next-generation devices."

Solving a memristor mystery to improve energy-efficient, long-lasting memory devices
Los Angeles CA (SPX) Sep 15, 2024
Researchers from the University of Michigan have uncovered new insights into how memristors - electrical components that store data using electrical resistance - retain information even after power is cut off. Their study, published in 'Matter', reveals that phase separation, a process where molecules separate like oil and water, and oxygen diffusion play key roles in helping memristors preserve data. Up until now, scientists have struggled to explain how memristors maintain nonvolatile memory, as ... read more
