Spintronics/Magnetotronics Used In Circuit Design

Click For Summary

Discussion Overview

The discussion centers around the topic of spintronics and its applications in circuit design, particularly in the context of a research assignment for an electrical engineering class. Participants share resources, insights, and questions related to the theoretical and practical aspects of spintronics, including its potential uses in memory storage and quantum computing.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant seeks knowledge and references on spintronics for a technical report, expressing a lack of extensive prior knowledge on the topic.
  • Another participant, who has industry experience, requests web pointers for learning about spintronics.
  • It is noted that spintronic devices operate based on electron spin, with some claiming functional demo devices exist, though practical applications may be limited.
  • Participants mention the challenge of finding understandable introductory articles due to the technical nature of current research in spintronics.
  • Specific references to articles and journals are provided, including a descriptive article from IEEE Spectrum and a technical paper from IEE Proceedings.
  • A summary of spintronic device operation is shared, highlighting the process of storing, carrying, and reading information via electron spins, and its implications for memory storage and quantum computing.
  • One participant expresses a desire for additional sources to avoid plagiarism and seeks guidance on structuring a technical report, particularly on the advantages of spintronics over traditional transistor circuits and photonic systems.
  • Another participant expresses appreciation for the information shared in the discussion.

Areas of Agreement / Disagreement

Participants generally agree on the potential of spintronics and the challenges in finding accessible information, but there is no consensus on the practical applications or the current state of research in the field.

Contextual Notes

Participants note the complexity of current research and the difficulty in finding introductory materials, indicating that the field is still developing and may have unresolved technical aspects.

Hi guys, haven't really posted here much; but I've read a couple topics. I have been assigned a research topic in my EE class (2ndyear) and I choose to do it on spintronics. I have to write a ten page technical report on my chosen subject. Now, as I am without extensive knowledge of any of the listed topics (of around 50), I chose the one that appealed to me the most. I've done some minor research on it (just a couple google searches to see what it was all about); but was wondering if you could offer any knowledge/references/articles/journals about it; or resources that you use to find technical information without having to preform research labs and experiments yourselves. Thanks for any help you can lend me.

Well, as an EE in industry for a couple years who's never heard of the subject, could you please provide a couple web pointers? Thank you.
 
It's devices that operate with electron spin.
I've seen a few articals on it.
You may find some additional information under quantum computing and qubit.


I don't think you will find any technical information on this (in the sense of practical application).
It is pretty new as a research area, but some people are claiming functional demo devices.
 
There is much current research that is highly technical, so the challenge is finding understandable introductory articles. IEEE Spectrum had a descriptive article on spin transistors in Dec. 2001.

More technical is
Spintronics device concepts
Circuits, Devices and Systems, IEE Proceedings [see also IEE Proceedings G- Circuits, Devices and Systems]
Volume 152, Issue 4, 5 Aug. 2005 Page(s):312 - 322
IEE is a British journal but your library can access it. The references contain a few review articles as well.

This should get you started.
 
Thanks for your replies; and for Berkeman; here is a quick summary of some of the information I've found:

All spintronic devices act according to the simple scheme: (1) information is stored (written) into spins as a particular spin orientation (up or down), (2) the spins, being attached to mobile electrons, carry the information along a wire, and (3) the information is read at a terminal. Spin orientation of conduction electrons survives for a relatively long time (nanoseconds, compared to tens of femtoseconds during which electron momentum decays), which makes spintronic devices particularly attractive for memory storage and magnetic sensors applications, and, potentially for quantum computing where electron spin would represent a bit (called qubit) of information.

Scientific American has an article on this which was pretty useful (except that... it seems they've 'doubled' sections in some places...) located at:
http://www.sciam.com/article.cfm?articleID=0007A735-759A-1CDD-B4A8809EC588EEDF
It has an overview of what it is, how its being used, problems, and possibilities. But I would like additional sources so that I have lots of information to draw from in order to provide my profs with a distinct unplaigarized perspective.

And... based on technical reports; of which I have written precisely zero; I would like to know how you get started, and what 'point'/'purpose' (or thesis I guess... don't know what you use in technical documents per se) you try to explain in detail to your reader. I've decided that I would show the advantages of this system as opposed to current transistor circuits, and potentially, photonic systems (if I have enough time to research this area as well).
 
I learn something new every darned day here on the PF. Thanks for the info.
 
I'm writing a paper about this field. Thank U all
