The celebrated renaissance of the multiferroics family over the past ten years has also been
that of its most paradigmatic member, bismuth ferrite (BiFeO 3). Known since the 1960s to be …

Nonlinear optics is an essential component of modern laser systems and optoelectronic
devices. It has also emerged as an important tool in probing the electronic, vibrational …

BiFeO3 is one of the most studied multiferroic materials. Both its magnetic and ferroelectric
properties can be influenced by do**. A large body of work on the doped material has …

We measured the optical properties of epitaxial CoFe 2 O 4 thin films and compared our
findings with complementary electronic structure calculations and similar studies on the Ni …

Raman spectra, supplemented by powder x-ray diffraction and magnetization data of
isovalently A-and B-site substituted BiFeO 3 in the Bi 1− x La x FeO 3 (0≤ x≤ 1), Bi 1− x Tb …

In this work, we present a sol–gel synthesis of ε-Fe2O3 nano and microparticles stabilized in
silica thin films. Thanks to the relatively high size of the synthesized particles, we have been …

The angular dispersion of oblique phonon modes in a multiferroic BiFeO 3 has been
obtained from a micro-Raman spectroscopic investigation of a coarse grain ceramic sample …

Stimulus-responsive shape-memory materials have attracted tremendous research interests
recently, with much effort focused on improving their mechanical actuation. Driven by the …

Topological structures in multiferroic materials have recently received considerable attention
because of their potential use as nanoscale functional elements. Their reduced size in …

The phonon structure of antiferromagnetic Bi 2 Fe 4 O 9 (space group P bnm No. 55, TN≈
240 K) was studied theoretically by calculations of lattice dynamics and experimentally …
