Ba 0.67 Sr 0.33 ) 1-3x/2 Y x Ti 1-y/2 Mn y O 3 [BST(Mn ? Y), x = 0.006, y = 0.005] ceramics were fabricated by using citrate-nitrate combustion derived powder. Microstructure and dielectric properties of the BST(Mn ? Y) ceramic samples were investigated within the sintering temperature ranged from 1220 to 1300°C. Sintering temperature has a great influence on the microstructure and electrical properties of the ceramic samples. The dielectric properties, ferroelectric properties, and tunability are enhanced by optimizing sintering temperature. The relatively high tunability of 40 % (1.5 kV/mm DC field, 10 kHz) was obtained, and relatively low dielectric loss, \0.0052 (at 10 kHz, 20°C) was acquired for BST(Mn ? Y) samples sintered at 1275°C for 3 h. Both the low dielectric loss and enhanced tunable properties of BST(Mn ? Y) are useful for tunable devices application.

Mn/Y co-doped Ba 0.67 Sr 0.33 TiO 3 (Mn+Y: BST) thin films were deposited on LaNiO 3 (LNO)/SiO 2 /Si substrates without and with SrTiO 3 (STO) buffer layers by radio frequency (RF) magnetron sputtering technology. Influence of the STO buffer layer thickness on the properties of the Mn+Y: BST films was investigated. X-ray diffraction (XRD) and scanning electron microscopy (SEM) investigations revealed that all the films haveuniform and crack-free surface with a perovskite structure. The Mn+Y: BST films with STO buffer layer of 20 nm showed the best electrical properties. The improved properties have been attributed to the STO buffer layer.

“…Stoichiometric deviation is the most crucial problem existing in the two methods. Recently, the citrate gel method which is based on the Pechini-type route [12] has been widely used to prepare the powders [13,14]. However, to the best of our knowledge, this method involves too complex processes, and the powders obtained were always badly agglomerated.…”

“…The codoping is an effective way to optimize the electrical properties of Ba 1Àx Sr x TiO 3 ceramics [14], improving the ferroelectric properties and reducing the leakage current. For example, Mn/Y codoped BST capacitors exhibit improved ferroelectric properties and lower dielectric loss (tan d < 0.0073 at 1 kHz).…”
