Article Synopsis
  • * This study focuses on enhancing magnetoelectric coupling in multilayer heterostructures by applying multiple strain engineering techniques on piezoelectric crystals which led to record-high coupling coefficients.
  • * The findings indicate that large magnetoelectric responses can be achieved through magnetization changes influenced by strain and suggest a pathway for more energy-efficient magnetoelectric technologies.

Reducing the grain size of metals and ceramics can significantly increase strength and hardness, a phenomenon described by the Hall-Petch relationship. The many studies on the Hall-Petch relationship in metals reveal that when the grain size is reduced to tens of nanometers, this relationship breaks down. However, experimental data for nanocrystalline ceramics are scarce, and the existence of a breakdown is controversial.
