I have mostly seen composites made of piezoelectric ceramics layered with magnetostrictive alloys for the demonstration of the magneto-electric effect.
My understanding is that piezoceramics are typically softer (easier to deformation) and have a higher electromechanical coupling than piezoelectric single crystal materials like quartz and LiNbO3.
So they seem like a more obvious choice for magneto-electric devices.
But are there examples of magnetoelectric devices using a single crystal material layered with a magnetostrictive material? And would there be any benefits to this arrangement?
I am curious if any particular device structures might be beneficial, instead of just layering the materials.
Hi David,
there have been single crystalline piezomaterials like ZnO used for magnetoelectric sensors. The group of Prof. Adelung did a lot with single-crystalline ZnO needles. Have a look at https://www.tf.uni-kiel.de/matwis/fnano/de/Publications
You will find there a lot about the magnetoelectric sensing via pizeotronics!

I have seen 0-3 PZT/PvDF composites in the past.
