Availability of quantum materials as sufficiently large and high-quality single crystals holds
the key to understanding their physical properties, which is crucial for making future …

At sufficiently low temperatures, interacting electron systems tend to develop orders.
Exceptions are quantum critical point (QCP) and quantum spin liquid (QSL), where …

Two triangular lattice antiferromagnets Sr 3 Co (Nb, Ta) 2 O 9 with an effective j eff= 1/2 of
Co 2+ are synthesized and their magnetic properties are investigated via magnetization and …

The interplay between competing degrees of freedom can stabilize nontrivial magnetic
states in correlated electron materials. Frustration-induced strong quantum fluctuations can …

We report a comprehensive temperature-dependent investigation of the 1: 2 ordered triple
perovskite system Sr 3 Ca Ru 2 O 9. It crystallizes in the monoclinic structure with space …

The layered triangular lattice owing to 1: 2 order of B and B′ sites in the triple perovskite A
3 BB 2′ O 9 family provides an enticing domain for exploring the complex phenomena of …

Here, we report both ac and dc magnetization, thermodynamic, and electric properties of
hexagonal Ba 3 NiIr 2 O 9. Ni 2+(spin 1) forms a layered triangular lattice and interacts …

We present an experimental investigation of the magnetic ground state in Ba 4 NbIr 3 O 12,
a fractional valent trimer iridate. X-ray absorption and photoemission spectroscopy show that …

Here, we report detailed lattice structure, magnetization (dc and ac) and specific heat
measurements on a 3d-5d based new triple-perovskite material Sr 3 CuIr 2 O 9. The Sr/Cu …

Recently, there have been contrary claims of Kitaev spin-liquid behavior and ordered
behavior in the honeycomb compound Ag 3 Li Ir 2 O 6 based on various experimental …
