摘要

The present study explores the systematic investigation of magnetoelectric coupling and magnetic field sensing characteristics of 2-2 layered Ni50Mn35In15/Pb0.96La0.04(Zr0.52Ti0.48) O-3 (Ni-Mn-In/PLZT) multiferroic heterostructure fabricated over Si substrate via DC/RF magnetron sputtering technique. The temperature-dependent dielectric constant curve depicts a typical hump-like structure in the temperature range of 266-283K, which overlaps with the Ni-Mn-In martensite transformation region. The magnetoelectric coupling coefficient (alpha(ME)) as a function of crucial factors such as DC bias magnetic field, AC magnetic field and its frequency are also analyzed and well explained. A alpha(ME) of similar to 1.2 V cm(-1) Oe is observed at similar to 400 Oe bias magnetic field. The multiferroic heterostructure exhibits excellent magnetic field sensing parameters with sensitivity, correlation coefficient (r(2)), hysteresis and inaccuracy of similar to 0.58 mV Oe(-1), 0.9992, 1.46% full-scale output (FSO) and 2.4% FSO, respectively. Such Si-integrated Ni-Mn-In/PLZT thin-film-based multiferroic heterostructures are useful for magnetic field sensing and nanoelectromechanical system device applications at room temperature.
