The magnetic, thermodynamic and dielectric properties of the γ -Fe2WO6 system is reported. Crystallizing in the centrosymmetric Pbcn space group, this particular polymorph exhibits a number of different magnetic transitions, all of which are seen to

We report the magnetic and dielectric properties of the spin-1 honeycomb lattice compound Pb6Ni9(TeO6)5. It crystallizes in hexagonal structure with a non-centrosymmetric space group P6322. DC magnetic susceptibility, AC magnetic susceptibility, and
We present magnetic, thermodynamic, dielectric and structural investigations on the aluminoborate Ni${_2}$AlBO${_5}$, belonging to the ludwigite family. Room temperature structural refinement suggests that the system crystallizes in the orthorhombic

We critically investigate the purported existence of a multiglass state in the quantum paraelectrics $\mathrm{SrTiO}{}_{3}$ and $\mathrm{KTaO}{}_{3}$ doped with magnetic $3d$ transition metals. We observe that the transition metals have limited solub

In transition metal oxides, quantum confinement arising from a large surface to volume ratio often gives rise to novel physico-chemical properties at nanoscale. Their size dependent properties have potential applications in diverse areas, including t

An oxyborate $\mathrm{Co}{}_{2}{\mathrm{AlBO}}_{5}$ belonging to the ludwigite family is investigated using structural, thermodynamic, dielectric, and magnetic measurements. Magnetic measurements indicate that this system is seen to exhibit long-rang

Samarium orthoferrite $(\mathrm{SmFe}{\mathrm{O}}_{3})$ has been the subject of debate on the existence or nonexistence of ferroelectric properties. It has a high spin-reorientation transition temperature ${T}_{\mathrm{SR}}$ (480 K). Detailed synchro

Magneto-dielectric spectra of La0.95Ca0.05CoO3 covering the crossover of spin states reveals strong coupling of its spin and dipolar degrees of freedom. Signature of spin-state transition at 30K clearly manifests in magnetization, supported by Co L_3
We report the observation of a Griffiths Phase in the geometrically frustrated antiferromagnet DyBaCo${_4}$O${_{7+\delta}}$. Its onset is determined using measurements of the thermoremanent magnetization, which is shown to be superior to conventional
