## Description

- description: "Perovskite-type EuTiO3, which is quantum paraelectric and \U0001D43A-type
    antiferromagnetic (AFM) in the bulk form, has attracted great attention due to
    its strong spin-lattice coupling and strain-induced multiferroic in thin film
    form. In this study, significant magnetodielectric (MD) coupling is demonstrated
    in K2NiF4-type ferromagnetic (FM) layered perovskite Eu2TiO4. Remarkably, an applied
    magnetic field induces a substantial increase in permittivity at \U0001D447C,
    which is three times larger than that observed in bulk EuTiO3. Our experimental
    and first-principles studies reveal that the insertion of EuO layers in Eu2TiO4
    enhances the Eu-\U0001D453/Ti-\U0001D451 orbitals hybridization through pseudostrain
    in the EuTiO3 layers, as well as modifies the magnetic exchange paths that favor
    ferromagnetism over antiferromagnetism. Our findings demonstrate the potential
    of layered structure to control MD coupling, paving the way for new strategies
    in designing MD materials."
