An improved magnetoelectric composite which incorporates LaSrMn or LaCaMn oxides as a magnetostrictive composition are described. The magnetostrictive composition preferably has the formula La<SUB>0.7</SUB>Sr<SUB>0.3</SUB>MnO<SUB>3 </SUB>or La<SUB>0.7</SUB>Ca<SUB>0.3</SUB>MnO<SUB>3</SUB>. The composites preferably have a magnetostrictive layer joined to a piezoelectric layer. The composites are useful for sensors, read-heads, storage media and high frequency transducer devices.
