Year: 2013
Abstract:
In this paper nanopowders of HoBa2Cu3O7-ä have been prepared by a citrate gel modification of the sol–gel technique. in order to optimize the prepration conditions. the precursor was put under different thermal treatments. ...
Effect of pure oxygen, argon and air in sintering on structural and magnetic properties of Nickle ferrite thin films prepared by spray pyrolysis
Year: 2013
Abstract:
In this study, nickel ferrite thin films were prepared on glass substrate by spray pyrolysis at 400 °C. The structural and magnetic properties of the samples were studied after calcination at argon, pure oxygen and air ...
