Looking for information on piezomagnetic materials

[lostminty]

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.

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!

Here find 13 papers mentioning the term "piezomagnetism":

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.
