Discussion Overview

The discussion revolves around piezomagnetic materials, specifically their properties and the strength of fields that can be produced through piezomagnetism. Participants explore the distinction between piezomagnetic and piezoelectric materials, as well as the current state of research on these topics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks to understand the strength of fields produced by piezomagnetic materials, indicating a lack of available information.
  • Another participant suggests that the inquiry may actually pertain to piezoelectric materials, providing links to resources on piezoelectricity.
  • A participant clarifies that they are indeed asking about piezomagnetic materials and references a Wikipedia article on the topic.
  • Further contributions include links to academic papers discussing piezomagnetism, indicating ongoing research in the field.
  • One participant mentions a journal article that discusses the scalar coefficient related to field intensity during poling, expressing uncertainty about the specific field strengths involved.

Areas of Agreement / Disagreement

There is a disagreement regarding the initial interpretation of the inquiry, with some participants suggesting piezoelectricity while the original poster insists on piezomagnetism. The discussion remains unresolved regarding the specifics of field strengths in piezomagnetic materials.

Contextual Notes

Participants have not reached a consensus on the definitions and implications of piezomagnetism versus piezoelectricity, and there are unresolved questions about the specific field strengths and coefficients related to piezomagnetic materials.

Could someone help me understand the strength of fields that can be produced with piezomagnetism?

I have not had much luck with searches for these materials.
 
Physics news on Phys.org
lostminty, welcome to Physics Forums. I am pretty sure you are asking about Piezoelectric materials and not “piezomagnetism”. If so, a quick Google search brought me these two sites:

This first one describes the basic science of piezoelectricity. If you compress the material it will generate a voltage, or if you apply a voltage it will expand or contract. See: http://www.piezomaterials.com/

This wikipedia site is detailed and an excellent source for you to study: http://en.wikipedia.org/wiki/Piezoelectricity

If you have further questions or doubts post them here. Google and Wikipedia are your friends…learn to use them to help you learn new things. Good luck!
 
Hi, no I am definitely asking about piezomagnetic materials

http://en.wikipedia.org/wiki/Piezomagnetism

They seem pretty recent, I've looked up articles from my uni's search engine. There is a lot of study with piezoelectric/piezomagnetic composites.
 
Excuse me. Thanks for the new news! I will study up whatever I can find!
 
I found one journal article where they were measuring the scalar coefficient, it was highly affected by what I think was the field intensity during poling. It wasn't clear to me what kind of field strengths were being produced. Might try finding it again...or if i could find the equation for coefficients that would be good.
