Magnetic properties lithium-doped manganite single crystals

Dielectric properties of lithium niobate single crystals doped with gadolinium

In this paper dielectric properties of LiNbO3:Gd single crystals at temperatures ~ 290–490 K at narrow frequency range (0.5–10 6 Hz) are presented. The influence of growth conditions was also investigated. The anomalies on dielectric plots depend on the development of the microand nano-domain structure.

Holographic properties of doubly doped lithium niobate crystals with Indium

The holographic properties of doubly doped lithium niobate crystals with Indium have been investigated. It is found that doping slight Indium concentration (0.5mol%) in LiNbO3:In, Fe crystal can efficiently increase the sensitivity with small dynamic range changing. To improve the whole holographic properties of LiNbO3 crystal, LiNbO3:In, Fe with ideal doping concentrations and a new photorefra...

Conductivity and switching phenomena in Mn-doped perovskite single crystals and manganite thin films

For better understanding of the charge-transport mechanisms in perovskite manganites, along with colossal magnetoresistance ~CMR! materials, such as La12xSrxMnO3, we study systems with decreased content of Mn ions, such as single crystals of LaGa12xMnxO3 (0,x,0.5). The conductivity of all the systems in study can be described adequately with a nonadiabatic approximation of the hopping model wit...

Magnetic Properties of Lu2Co17-xSix Single Crystals

Abstract. Magnetic properties of Lu2Co17-xSix single crystals grown by the Czochralski method were investigated. The homogeneity range of Si substitution for Co extends up to x = 3.4. The unit cell volume, V, Curie temperature, TC, and spontaneous magnetic moment, Ms, decrease monotonously with increasing Si content. Upon Si substitution, the spin-reorientation transition occurring in Lu2Co17 a...
