Magnetic interactions in disordered perovskite PbFe1/2Nb1/2O3 and related compounds: dominance of nearest-neighbor interaction
From theoretical calculations and modeling the main magnetic interactions were determined in Pb(Fe1/2Nb1/2)O3 and related compounds. It was shown dominance of nearest-neighbor interaction. The relatively h...

17O and 93Nb NMR investigation of magnetoelectric effect in Pb(Fe1/2 Nb1/2)O3./sub
The 17O and 93Nb quadrupole perturbed NMR spectra of multiferroic Pb(Fe1/2Nb1/2)O3 have been measured. The results show that the ordering at TN = 143 K is antiferromagnetic with spin canting and that there...

Lattice dynamics and broad-band dielectric properties of multiferroic Pb(Fe1/2Nb1/2)O3 ceramics
Complex dielectric properties of Pb(Fe1/2Nb1/2)O3 ceramics were investigated in a broad frequency range from 100 Hz up to 90 THz. A dielectric relaxation, which appears in THz region below 700 K, slows dow...

Raman study of 0.62Pb(Fe1/2Nb1/2)O3?0.38PbTiO3 single crystal
Polarized Raman scattering microscopy investigations of tetragonal single crystal of PFN-38PT allowed us to characterize the Raman signature of distinct ferroelastic domains. The analysis of the incident and scattered light polarization allowed us to...

Details of magnetic properties in Pb(Fe1/2Nb1/2)O3./sub
For Pb(Fe0:5Nb0:5)O3 the $magnetization measurements up to 70 kOe were performed with the aim to estimate the antiferromagnetic (AFM) and superantiferromagnetic (SAF) contribution to $magnetization. Below TN the increase of$magnetiz...
