Probing ferroic transitions in a multiferroic framework family: a neutron diffraction study of the ammonium transition metal formates.

Oxyhalides: A new class of high-TC multiferroic materials

Magnetoelectric multiferroics have attracted enormous attention in the past years because of their high potential for applications in electronic devices, which arises from the intrinsic coupling between magnetic and ferroelectric ordering parameters. The initial finding in TbMnO3 has triggered the search for other multiferroics with higher ordering temperatures and strong magnetoelectric coupli...

Dynamic Strain in Epitaxial Ferroic Oxide Films — @bulletorkidia Multiferroic Materials Based on Artificial Thin Film Het- Erostructures —

Epitaxial strain is known or theoretically predicted to essentially influence the electronic properties of transition metal perovskite oxides like (Ba,Sr)TiO3. One approach for reversible biaxial strain variation in epitaxial films fitting to a pseudocubic lattice parameter of about 4.0 Angstrom is the utilization of a ferroand piezoelectric PMN-PT(001) substrate. (PMN-PT stands for 0.72PbMg1/3...

Three-dimensional magnetic correlations in multiferroic LuFe2O4.

We present single crystal neutron diffraction measurements on multiferroic LuFe(2)O(4). Magnetic reflections are observed below transitions at 240 and 175 K indicating that the magnetic interactions in LuFe(2)O(4) are three-dimensional in character. The magnetic structure is refined as a ferrimagnetic spin configuration below the 240 K transition. Below 175 K a significant broadening of the mag...

In this paper, the effect of nanocatalytic metal-organic framework based on copper metal and bis-tetrazolamine (CuBTA) ligand functionalized with cobalt (II) oxide nanoparticles on the thermal decomposition behavior of ammonium perchlorate (AP), using differential survey calorimetry (DSC) has been reviewed. First, the metal-organic framework (CuBTA) was synthesized from the raw materials of cop...

Ternary transition metal chalcogenides with framework structures and the characterization of their bonding by magnetic properties

An extended Zinti principle is discussed for framework structures of ternary metal chalcogenides, pnictides and hydrides with tetrahedral and planar coordination of transition metal atoms. Their bonding can be characterized by the magnetic moments measured by susceptibilities and neutron diffraction. The experimental results are compared with crystal field splittings obtained by calculations ba...
