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.

Piezomagnetic materials are substances that exhibit both piezoelectric and magnetic properties. This means that they can generate an electric charge when subjected to mechanical stress, and they also respond to magnetic fields by changing their shape or size.
Piezomagnetic materials work by utilizing the magnetostriction effect, which is the ability of certain materials to change their shape or dimensions in response to a magnetic field. This change in shape or size leads to a corresponding change in the magnetic properties of the material.
Piezomagnetic materials are commonly used in various sensing and actuation applications. They are used to create high-precision sensors, such as strain gauges and accelerometers, as well as in medical devices, robotics, and energy harvesting systems.
Piezomagnetic materials and piezoelectric materials both exhibit the ability to generate an electric charge when subjected to mechanical stress. However, piezomagnetic materials also respond to magnetic fields, while piezoelectric materials do not.
Some common examples of piezomagnetic materials include nickel, cobalt, and iron alloys. Other materials such as Terfenol-D, a terbium-iron-dysprosium alloy, and Metglas, an amorphous metallic glass, also exhibit piezomagnetic properties.
