We present the synthesis and a detailed investigation of structural and magnetic properties of polycrystalline NH4[(V2O3)(2)(4,4' -bpy)(2)(H2PO4)(PO4)(2)] 0.5H(2)O by means of x-ray diffraction, magnetic susceptibility, electron spin resonance, and P

The structure of K2Ni2(MoO4)(3) consists of S = 1 tetramers formed by Ni2+ ions. The magnetic susceptibility chi(T) and specific heat CP (T) data on a single crystal show a broad maximum due to the low dimensionality of the system with short-range sp

We present microscopic magnetic properties of a two-dimensional triangular lattice Sc2Ga2CuO7, consisting of single and double triangular Cu planes. An antiferromagnetic (AFM) exchange interaction J/k(B) approximate to 35 K between Cu2+ (S = 1/2) spi

BaV3O8 contains both magnetic V4+(S=1/2) ions and non-magnetic V5+(S=0) ions. The V4+ ions are arranged in a coupled Majumdar-Ghosh chain like network. Our magnetic susceptibility chi(T) data fit well with the Curie-Weiss formula in the temperature r

PHYSICAL REVIEW B
We report the structural and magnetic properties of the 4d (M = Rh) based and 5d ( M = Ir) based systems Ba3MxTi3-xO9 ( nominally x = 0.5, 1). The studied compositions were found to crystallize in a hexagonal structure with the centrosymmetric space

Ba3IrTi2O9 crystallizes in a hexagonal structure consisting of a layered triangular arrangement of Ir4+(J(eff) = 1/2). Magnetic susceptibility and heat capacity data show no magnetic ordering down to 0.35 K in spite of a strong magnetic coupling as e

We present a 31P NMR study of the coupled spin 1/2 ladder compound BiCu2PO6. In the pure material, intrinsic susceptibility and dynamics show a spin gap of about . Substitution of non magnetic Zn or magnetic Ni impurity at Cu site induces a staggered

We report a mu SR study of LiCrO(2), which has a magnetic lattice made up of a stacking of triangular Heisenberg antiferromagnetic (Cr(3+), S=3/2) layers. A static magnetically ordered state is observed below the transition temperature T(N)=62 K, whi

A detailed experimental as well as theoretical study is carried out to elucidate the origin of the spin gap in the quasi-one-dimensional compound BaCu(2)V(2)O(8). Our experimental analysis with the aid of careful magnetic susceptibility measurements

We report Li-7 NMR, magnetic susceptibility, and heat capacity measurements on the triangular lattice Heisenberg antiferromagnet compound LiCrO2. We find that in contrast to NaCrO2, magnetic properties of LiCrO2 have a more pronounced three dimension
