This review aims to summarize more than 100 years of research on spinel compounds,
mainly focusing on the progress in understanding their magnetic, electronic, and polar …

Small-angle neutron scattering (SANS) is one of the most important techniques for
microstructure determination, being utilized in a wide range of scientific disciplines, such as …

A unique type of frustrated lattice is found in two A-site ordered spinel oxides, LiGaCr 4 O 8
and LiInCr 4 O 8. Because of the large size mismatch between Li+ and Ga 3+/In 3+ ions at …

The spinel crystal system, AB 2 O 4, has been fertile ground in studying the effects of
magnetic and orbital frustration. The experimental findings, with primary focus on neutron …

Conventional crystalline magnets are characterized by symmetry breaking and normal
modes of excitation called magnons, with quantized angular momentum ħ. Neutron …

We present the results of band structure calculations for A Cr 2 X 4 (A= Zn, Cd, Hg and X= O,
S, Se) spinels. Effective exchange coupling constants between Cr spins are determined by …

Dynamical properties of the lattice structure were studied by optical spectroscopy in A Cr 2 O
4 chromium spinel oxide magnetic semiconductors over a broad temperature region of T …

We present temperature-, magnetic-field-, and pressure-dependent Raman scattering
studies of single crystal Mn 3 O 4, combined with temperature-and field-dependent x-ray …

Dy 2 Ti 2 O 7 is a geometrically frustrated magnetic material with a strongly correlated spin
ice regime that extends from 1 K down to as low as 60 mK. The diffuse elastic neutron …

The temperature dependence of eigenfrequencies and intensities of the infrared (IR) active
modes has been investigated for the antiferromagnetic chromium spinel compounds CdCr 2 …
