Abstract

A polycrystalline ZnO film is fabricated on a cantilevered substrate of silicon by pulsed laser deposition (PLD) technique and investigated the electrostrictive and magnetostrictive (in-plane and out-of-plane) properties by an indigenously developed optical cantilever beam magnetometer (CBM) setup. The film shows excellent electrostrictive as well as magnetostrictive response at room temperature (300 K) with high values of piezoelectric strain coefficient (

| d |

= 69.69 p.m./V), piezoelectric stress coefficient (

| e |

= 7.75 C/m²), saturation magnetostriction (

λ_{s}

= 1286.15 ppm & 647.99 ppm), and strain sensitivity (dλ/dH = 12.63 × 10 ⁻⁹ A⁻¹m & 8.29 × 10 ⁻⁹ A⁻¹m) in in-plane and out-of-plane configuration, respectively. The emergence of significant electrostrictive and magnetostrictive responses makes the ZnO film well suited for use as a ferroelectric (FE) or as a ferromagnetic (FM) material in electric field-controlled multiferroic magnetoelectric composites (i.e., FM/FE heterostructure) applicable for the development of novel spintronic devices.

期刊介绍： Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications. Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques. Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals. Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review. The Journal is owned by the Korean Physical Society.
