Exchange coupled CoFe/BiFeO3 thin-film heterostructures show great promise for power-efficient electric field-induced 180° magnetization switching. However, the coupling mechanism and precise qualification of exchange in have been elusive. Here we direct evidence field control magnetic state through field-dependent ferromagnetic resonance spectroscopy nanoscale spatially resolved imaging. Scanning electron microscopy with polarization analysis images reveal CoFe layer to canted moment BiFeO3...
Strain has been widely used to manipulate the properties of various kinds materials, such as ferroelectrics, semiconductors, superconductors, magnetic materials and "strain engineering" become a very active field. For strain-based information storage, non-volatile strain is useful highly desired. However, in most cases, induced by converse piezoelectric effect volatile.

A strain-driven orthorhombic (O) to rhombohedral (R) phase transition is reported in La-doped BiFeO3 thin films on silicon substrates. Biaxial compressive epitaxial strain found stabilize the at La concentrations beyond morphotropic boundary (MPB).

Climatic impacts of historical volcanism are principally tied to the eruption size, while observation versus model discrepancies have been commonly attributed uncertainties in paleo‐ reconstruction or malpresentation volcanic aerosols models.

Dielectric response of Y3Fe5O12 ceramics was investigated over broad temperature and frequency ranges. Three dielectric relaxations were identified in the range from 125to620K. A Debye-type relaxation at low temperatures (125–320K) with an activation energy 0.29eV is shown to originate carrier hopping process between Fe2+ Fe3+. In a higher (320–620K), (f≦10kHz) 0.84eV most likely arises inhomogeneous structure, such as grain boundaries. Another wider has similar conduction (Ea=1.00eV)...
Abstract Voltage controlled 180° magnetization reversal has been achieved in BiFeO3-based multiferroic heterostructures, which is promising for the future development of low-power spintronic devices. However, all existing reports involve use an in-plane voltage that unfavorable practical device applications.

Multiferroic Pb(Zr,Ti)O3–CoFe2O4 (PZT–CFO) bilayer films with different residual stress status and oriented PZT layers were prepared on (111)Pt/Si substrate via a simple sol–gel spin-coating processing. Different heat-treatment processing resulted in orientation growth of the layer films, which affects magnetoelectric (ME) coupling PZT–CFO films. Both magnetic-field-induced shifts phonon vibration modes direct ME effect observed these demonstrate stress-mediated mechanism multiferroic
The converse magnetoelectric (ME) effect was investigated in bi-layered Ni/Pb(Zr0.52Ti0.48)O3 (PZT) thin films grown on Si substrates, with different thicknesses of Ni layers. By using an AC-mode magneto-optical Kerr method, it revealed that the electric-voltage induced magnetization variation dependent thickness layer. results showed Ni/PZT bilayered thick (about 40 nm) presented a dominative strain mediated ME coupling, whereas interface-charge and co-mediated coupling might coexist...
