400℃下在马弗炉中干燥反应试剂Y2O3、CuO、BaCO3 2h。准确称取05g BaCO3和相应量的Y2O3、CuO(Y∶Ba∶Cu＝1∶2∶3)，在干净的乳钵中研磨反应物直至没有见到白色的片状固体(大约需要10min)。模压1～3个混合物小圆片(d＝13mm，厚1～2mm)，置于氧化铝舟中。使用程序控制的电炉按下列步骤进行加热：

(1)加热到930℃，维持12h；

(2)冷却到500℃，维持1h；

(3)以每小时50℃的速度降温到400℃；

(4)冷却到室温。

当炉子温度低于400℃，可以用钳子取出样品，放在绝缘板上冷却。

Characterization of MBa2Cu3O7-x thin films by Raman microspectroscopy.

Appl. Spectrosc. 59(5) , 639-49, (2005)

Thin film embodiments of MBa2Cu3O7-x (MBCO, M = yttrium or a rare-earth metal) prepared by several different deposition methods on a variety of substrates were investigated by Raman microspectroscopy....

Coexistence of ferromagnetism and superconductivity in YBCO nanoparticles.

Phys. Chem. Chem. Phys. 14(11) , 3859-63, (2012)

Nanoparticles of superconducting YBa(2)Cu(3)O(7-δ) were synthesized via a citrate pyrolysis technique. Room temperature ferromagnetism was revealed in the samples by a vibrating sample magnetometer. E...
