Multiferroics, compounds with both magnetic and ferroelectric orders, are believed to be a
key material system to achieve cross-control between magnetism and electricity in a solid …

We have investigated the variation of induced ferroelectric polarization under a magnetic
field with various directions and magnitudes in a staggered antiferromagnet Ba 2 CoGe 2 O …

The coupling between spins and electric dipoles governs magnetoelectric phenomena in
multiferroics. The dynamical magnetoelectric effect, which is an inherent attribute of the spin …

We have investigated the magnetoelectric properties originating from the spin-dependent
hybridization between transition metal (X) d orbital and ligand ion p orbitals in the …

We studied spin excitations in the magnetically ordered phase of the noncentrosymmetric Ba
2 CoGe 2 O 7 in high magnetic fields up to 33 T. In the electron spin resonance and far …

Ba 2 ZnSi 2 O 7 ceramics with a monoclinic structure (C 2/c) were prepared using the
conventional solid-state method at 1200° C for 3 h in air. The as-prepared ceramics show …

We investigate magnetic excitations in Ba 2 CoGe 2 O 7. In terahertz absorption experiments
of the compound, novel magnetic excitations, ie, conventional magnetic resonance at 2 meV …

Oxides containing magnetic 3d transition metals offer a large family of structures with
frustrated magnetic networks. Some of those incommensurate antiferromagnetic structures …

Abstract Ba 1-x Sr x Cu 2 Si 2 O 7 solid solutions with melilite-type structure were
synthesized by solid-state reaction method. The Rietveld refinement, PVL theory and …

Exotic spin-multipolar ordering in spin transition metal insulators has so far eluded
unambiguous experimental observation. A less studied, but perhaps more feasible …
