Van der Waals 2D electronic and magnetic materials are here to stay. They are fundamentally of very high interest. For those of us passionate about magnetism and thin films over the years are like a heavenly refresh of the field. Almost everyone is convinced they will bring unique opportunities in spintronic devices etc.
What are the actual or potential advantages of hybrid or all van-der-Waals spintronic devices versus today state-of-the-art MTJs, MRAMs, SOT-devices? What specs they will beat current structures?
Would an all van-der Waals device have immediate advantages recognizable today, or those will come at some point in the future with emerging physics to be in the future found or implemented but that we still do not control or understand suffciently?
What do you think?
Greetings from Barcelona area everyone,
Here is one reference on current state of the art SOT-MRAM
high RA Dual MTH SOT-MRAM devices for high speed (10ns) compute-in-memory applications, M.Y. Song et al, IEEE 2023
- DOI:10.1109/IEDM45741.2023.10413832
These questions are excellent, and it's something everyone working on spintronics with vdW magnets considers. We've questioned ourselves on the advantages that vdW magnets can bring as well. Currently, it's challenging to provide a definitive answer because while vdW magnets offer numerous opportunities for spintronics, concrete beneficial examples are still emerging. Here's my perspective:
At present, it's more practical to appreciate the broad opportunities vdW magnets offer for advancing spintronics, generating new ideas, concepts, and physics that accelerate the field's development.
These points are my shallow understandings.
