Journal of Magnetism and Magnetic Materials

The structural properties have been investigated using XRD and FSEM data. Microstructure and chemical composition were determined by Scanning Electron Microscopy (SEM), which includes an energy dispersive X-ray diffractometer (EDX). Dielectric properties is assessed with the dielectric constant, temperature dependent capacitance and resistance. The magnetic property is assessed with the ac permeability and dc magnetization measurements.

The magnetic properties of Ba3TiRu2O9 , whose crystal structure is based on stacked triangular planar lattices of MO6 dimers and single MO6 octahedra, are reported. The system is magnetically disturbed by a substantial amount of Ti/Ru chemical disorder. The Weiss temperature and effective magnetic moment were found to be -29.5 K and 1.82 μB/f.u. respectively, and a bifurcation in the zero field cooled and field cooled magnetic susceptibility is observed below 4.7 K, suggesting that this is a compositionally-disordered spin-glass system. The material is a semiconductor with an activation energy for charge transport of approximately 0.14 eV.

2.1. Synthesis of CoO nanoparticles Cobalt acetate tetrahydrate (CAT), Co(CH3COO)2.4H2O (≥ 99 %) purchased from Sisco Research Laboratories Pvt. Ltd, OA (70%) and TOP (90%) from Sigma Aldrich were used as-received for preparation of CoO NPs. 2.1.1 First Method Typically, 2 g CAT, 8 ml OA and 2 ml TOP are mixed in three neck round-bottom flask and heated at the rate of 10 0C/min in nitrogen atmosphere. The pink-like crystals of CAT start to decompose turning solution colour to light blue around at 80 0C, to dark blue with increase in temper-ature and finally to dark brown at around 180 0C up to 200 0C at which 2 h is maintained; this indicates the formation of NPs. This solution is then cooled to 30oC, and centri-fuged by adding n-hexane to extract and wash the NPs. The washing is performed three times for remove the ac-cess OA and TOP, not bound on NPs surface. The particles dried at 60oC in vacuum drier are used for various charac-terizations. This sample was coded as CoO1. Another sam-ple prepared at 230 0C while other reaction conditions re-maining the same is coded as CoO2. 2.1.2 Second Method 0.25 ml of preheated TOP at 200oC is added in a solution of 2 g CAT and 8 ml OA, already degassed at 120-130oC for 30 min. The resulting solution is further heated to 230oC for 5.5 h under nitrogen atmosphere. The pink colour of CAT changes to blue and finally to a brownish colour due to the formation of CoO NPs. Cooling down to 30 oC, the reaction product is then washed and dried similarly as above; sample is denoted as CoO3. Other samples coded as CoO4, CoO5, CoO6, CoO7 and CoO8 for TOP concen-tration of 0.25 ml, 1 ml, 3 ml, 8 ml and 12 ml, respectively, with other conditions remaining the same are then prepared in 1.5 h. Additional samples coded as CoO9, CoO10 and CoO11 are then respectively prepared in 8 ml OA only, combination of 8 ml OA with 12 ml TOP, like CoO3, and 10 ml TOP only, at 260oC in 2 h in each with other condi-tions remaining the same to see the effect of surfactant/s and reaction temperate. To make NPs biocompatible, SiO2 was coated on the prepared powder of CoO8 using a standard method, described elsewhere23.
