Magnetic digital flop of ferroelectric domain with fixed spin chirality in a triangular lattice helimagnet

, 2009
Ferroelectric properties in magnetic fields of varying magnitude and direction have been investigated for a triangular-lattice helimagnet CuFe1-xGaxO2 (x=0.035). The magnetoelectric phase diagrams were deduced for magnetic fields along [001], [110], and [

Possible coexistence of Cycloidal Phases, Magnetic Field Reversal of Polarization and Memory Effect in Multiferroic \emph{R}$_{0.5}$Dy$_{0.5}$MnO$_3$ (\emph{R}=Eu and Gd)

, 2015
We report the occurrence of both \emph{ab} and \emph{bc} cycloidal ordering of Mn-spins at different temperatures and their possible coexistence at low temperatures in the polycrystalline mixed rare-earth compounds, \emph{R}$_{0.5}$Dy$_{0.5}$MnO$_3 ...

Effect of Copper Oxide on Dielectric and Magnetic Properties of Substituted Sr-M Hexaferrite [PDF]

, 2015
Effect of CuO addition on the hexagoal ferrite (SrCo1.3Ti1.3Fe9.4O12-d) has been investigated. (Co-Ti-Sr)- M hexaferrite compositions were synthesized by sol-gel auto combustion method. Pure ferrite phase was achieved after cacination at 1200°C.

The Conductivity and Dielectric Properties of Neobium Substituted Sr-Hexaferrites

Nanomaterials, 2019
The Nb3+ ion substituted Sr hexaferrites (SrNbxFe12−xO19 (x = 0.00−0.08) hexaferrites (HFs)) were fabricated via a citrate-assisted sol-gel approach. X-ray powder diffractometer analysis affirmed the pureness of all products.

Strontium hexaferrite platelets

Platelets of strontium hexaferrite (SrFeO, SFO), up to several micrometers in width, and tens of nanometers thick have been synthesized by a hydrothermal method. They have been studied by a combination of structural and magnetic techniques, with emphasis on Mössbauer spectroscopy and X-ray absorption based-measurements including spectroscopy and ...
