Structural, magnetic and magnetoelectric studies of BaTiO3:Co nanocomposite films formed by ion-beam methods

Особенности Структуры Нанокристаллических Пленок Никеля, Сформированных Методом Ионного Распыления

“…Тонкие пленки Ni осаждались методом ионного распыления (см. например [15]) на подложки из монокристаллического кремния с ориентацией (001). Как было установлено ранее, ориентация подложки не влияет на структурные параметры пленок из-за присутствия на ее поверхности естественной оксидной пленки SiO 2 [5].…”

Exchange bias mediated self-biased magnetoelectric coupling in Co–BaTiO3 composites

“…Most of the reported studies on multiferroic Co-BTO composites investigate the epitaxial layered structures with 2-2 connectivity. 3,4 These heterostructures were fabricated using different techniques such as molecular beam epitaxy, 3,5,6 ion beam sputtering, 7,8 RF magnetron sputtering, 4,9 pulsed laser deposition 4,10 and spin coating. 11 In 2008, Park et al reported the strain-mediated DME coupling in Co-BTO thin films wherein an enhancement of the ME output was observed with the increase in the frequency of the external AC magnetic field.…”

“…6 Meanwhile, Khalitov et al also studied ME coupling in BTO/Co films using FMR. 8 In 2014, Li et al synthesized Co/BTO nanofibers using electrospinning techniques and studied their magnetic properties. 15 In 2018, Rani et al investigated the DME coupling in Co-doped BTO and observed the highest ME coupling coefficient ( α ) of 3.39 mV cm −1 Oe −1 for 2.5 mol% doping of Co. 16 Recently, Buttlar et al reported the magnetoelectric coupling in the 0–3 composites of the Co–BTO system synthesized via the reduction of Co 3 O 4 and BTO under N 2 gas sintering.…”

Structural and magnetic studies of thin Fe57 films formed by ion beam assisted deposition

“…It is possible to produce films and coatings with a wide range of structural characteristics, different phase structures and physical and performance properties by varying such parameters as the deposition rate, substrate temperature, composition of the reaction gas, composition of the sputtering target, etc. Earlier we used these techniques to synthesize and modify diamond-like carbon films [4,5], to form silver nanoparticles in the silica glass matrix [6,7], to prepare nanocomposite films of barium titanatebased multiferroics with magnetic cobalt nanoparticles [8], to fabricate thin germanium layers on silicon [9,10] and nanostructured ZnO and Al 2 O 3 films [11]. The characteristic feature of abovelisted single-elemental or composite films and layers is the nanocrystalline structure (when the dimensions of the crystallites of different phases are in the nanometer range), which determines their optical, magnetic and electro-physical properties.…”
