The structure and dielectric properties of charge-ordered Nd 1.75 Sr 0.25 NiO 4 ceramics are presented. The giant dielectric constant about 30 000 is observed in the present ceramics even the frequency is up to 5 MHz. There are three dielectric relaxations at the curve of temperature dependence of d
By the method of capacitance spectroscopy and of magnetotransport we have investigated the = 1 3 and 2 3 fractionalquantum-Hall-e ect (FQHE) states in gated GaAs=AlGaAs heterojunctions with tuned electron areal density. Our experimental results conΓΏrm the theoretical prediction of the fractional qua
