T_N Dependence on Hole Concentration in the La_<2-x> Sr_x CuO_<4+δ> System

概要
- 論文の詳細を見る
Hole concentration, h, was determined by using the coulometric titration technique for the powdered samples of La_<2-x>Sr_xCuO_<4+δ>(0 ≤ x ≤ 0.02) annealed in flowing 1 atm N_2 and 1 atm O_2. From the temperature dependence of magnetic susceptibility we found that the Neel temperature, T_N, decreases steeply with increasing h and that T_N(h) can be fitted in the following expression T_N(h)/T_N(O)=1-{h/h_c}^n where T_N(O) , h_C and n are constants . This power-law dependence might be explained by finite size scaling theory.
