“…Further increase in the H DC results in decrement in the α ME value. Many researchers have also reported similar behavior of α ME as a function H DC [27,28]. This trend between α ME and H DC could be ascribed to the fact that the magnetostrictive response of the Ni-Mn-In layer increases to an optimum magnetic field and further increase in the magnetic field results in the saturation of the piezomagnetic coefficient.…”

“…The magnetic field sensing performance of multiferroic heterostructure is characterized by the magnetoelectric coupling coefficient (α ME ). Reports are available, which have calculated α ME in thin-film-based magnetoelectric sensors [11,[25][26][27][28][29][30]. However, α ME as a function of all possible parameters such as DC magnetic field, AC magnetic field and frequency are not collectively investigated in the literature [11,[29][30][31].…”

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) O3 (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 266–283 K, which overlaps with the Ni–Mn–In martensite transformation region. The magnetoelectric coupling coefficient (αME) 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 αME of ~1.2 V cm−1 Oe is observed at ~400 Oe bias magnetic field. The multiferroic heterostructure exhibits excellent magnetic field sensing parameters with sensitivity, correlation coefficient (r2), hysteresis and inaccuracy of ~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.

“…The system SrTiO 3 /NiFe 2 O 4 is known mostly for its capability as a visible-light-driven photocatalyst [ 7 , 8 ]. SrTiO 3 (STO) is a prototypical cubic perovskite oxide with unique physical properties, such as wide bandgap, high dielectric constant, thermal stability, and large permittivity [ 9 , 10 , 11 ]. Besides, SrTiO 3 is known as versatile powder support for the formation of heterostructures with specific properties for technological applications [ 12 , 13 , 14 , 15 , 16 ], because SrTiO 3 , as an intrinsic paraelectric, is able to stabilize ferroelectric order via substrate-induced strain, cation doping, 18 O isotope substitutions, and defect engineering [ 17 ].…”

In this research, we reported on the formation of highly porous foam SrTiO3/NiFe2O4 (100−xSTO/xNFO) heterostructure by joint solid-state and sol-gel auto-combustion techniques. The colloidal assembly process is discussed based on the weight ratio x (x = 0, 25, 50, 75, and 100 wt %) of NiFe2O4 in the 100−xSTO/xNFO system. We proposed a mechanism describing the highly porous framework formation involving the self-assembly of SrTiO3 due to the gelation process of the nickel ferrite. We used a series of spectrophotometric techniques, including powder X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), N2 adsorption isotherms method, UV-visible diffuse reflectance spectra (UV-Vis DRS), vibrating sample magnetometer (VSM), and dielectric measurements, to investigate the structural, morphological, optical, magnetic, and dielectric properties of the synthesized samples. As revealed by FE-SEM analysis and textural characteristics, SrTiO3-NiFe2O4 nanocomposite self-assembled into a porous foam with an internally well-defined porous structure. HRTEM characterization certifies the distinctive crystalline phases obtained and reveals that SrTiO3 and NiFe2O4 nanoparticles were closely connected. The specific magnetization, coercivity, and permittivity values are higher in the 75STO/25NFO heterostructure and do not decrease proportionally to the amount of non-magnetic SrTiO3 present in the composition of samples.
