Ferroic transitions in the multiferroic (1 −x)Pb(Fe1/2Nb1/2)O3–xPbTiO3 system and its phase diagram

Modified hydrothermal reaction (MHT) for CoV2O6·4H2O nanowire formation and the transformation to CoV2O6·2H2O single-crystals for antiferromagnetic ordering and spin-flop

“…The magnetization of the sample increases with decreasing temperature with a sharp peak around 14.9 K indicating an antiferromagnetic-like ordering as found in many antiferromagnetic systems. [32][33][34] As the temperature is decreased further, another antiferromagnetic-like peak has been observed around 6.8 K. It will be interesting to nd out the antiferromagnetic ground state of these transitions. It may arise due to competition between antiferromagnetic Co chains and ferromagnetic Co ions.…”

“…For the reader's convenience, Fig. 3 reports the magnetic and electric phase diagrams of PFN-xPT solid solution plotted on the base of published experimental data [2,4,7]. It is expected that further increase of the Ti concentration would weaken the AFM phase so that the negative PM-like (i.e.…”

“…For instance at the PT concentration x larger than about 10%, the long-range AFM ordering of Fe 3+ spins is suppressed [2] and the ferroelectric phase has tetragonal symmetry [4,7]. For the reader's convenience, Fig.…”

“…On cooling, PFN undergoes FE [4][5][6] and magnetic phase transitions 2,3,6,7 , it is supposed to have the FE relaxor- 6,8,9 or even birelaxor-properties 7 , while some of them might have extrinsic reasons 10 . First-principles calculations of the energies of different chemical configurations of PFN revealed an unusual effect of Fe nanoscale ordering 11 influencing magnetic properties of PFN 12,13 .…”
