Crucial Role of Site Disorder and Frustration in Unusual Magnetic Properties of Quasi-2D Triangular Lattice Antimonate Na4FeSbO6

The effect of antisite disorder in the layered sodium iron antimonate Na 4 FeSbO 6 was examined both experimentally and theoretically. The magnetic susceptibility and specific heat measurements show that Na 4 FeSbO 6 does not undergo a long-range antiferromagnetic order, unlike its structural analog Li 4 FeSbO 6 . The electron spin resonance yields the complicated picture of coexistence of two magnetic subsystems corresponding to two different Fe cation positions in the lattice (regular and antisite) and driving the magnetic properties of the Na 4 FeSbO 6 . This conclusion found perfect confirmation from both the Mössbauer and X-ray absorption data which

“…They reveal electric field-controllable magnetoelectric coupling via interfacial spin polarization of Ti 4 þ . Research on core-shell nanoparticles had shown that the spin polarization of Ti 4 þ at the interfaces between BTO and Fe and its oxides remains virtually negligible 4 . Hence, two-phase composites of a piezoelectric and a magnetostrictive phase, which can be magnetoelectrically coupled via stress mediation 5 , still remain favourites of the current discussion 6 .…”

Electric in-plane polarization in multiferroic CoFe2O4/BaTiO3 nanocomposite tuned by magnetic fields

et al. 2013

Ferrimagnetic CoFe 2 O 4 nanopillars embedded in a ferroelectric BaTiO 3 matrix are an example for a two-phase magnetoelectrically coupled system. They operate at room temperature and are free of any resource-critical rare-earth element, which makes them interesting for potential applications. Prior studies succeeded in showing strain-mediated coupling between the two subsystems. In particular, the electric properties can be tuned by magnetic fields and the magnetic properties by electric fields. Here we take the analysis of the coupling to a new level utilizing soft X-ray absorption spectroscopy and its associated linear dichroism. We demonstrate that an in-plane magnetic field breaks the tetragonal symmetry of the (1,3)-type CoFe 2 O 4 /BaTiO 3 structures and discuss it in terms of off-diagonal magnetostrictive-piezoelectric coupling. This coupling creates staggered in-plane components of the electric polarization, which are stable even at magnetic remanence due to hysteretic behaviour of structural changes in the BaTiO 3 matrix. The competing mechanisms of clamping and relaxation effects are discussed in detail.

“…The magnetic iron oxides, magnetite (Fe 3 O 4 ) and maghemite (c-Fe 2 O 3 ), have been receiving continuous attention in fundamental researches for their structural characteristics and physicochemical properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. In recent years, the preparation of water-soluble magnetic nanocrystals has evoked increasing interest for their applications in magnetic resonance imaging [15,16], wastewater and oil pollution treatments [17][18][19], thermal therapy [20,21], separation or purification of DNA or protein [22,23], and gene carriers or drug delivery [24][25][26][27][28], etc.…”
