Electronic and Magnetic Properties of Cation Ordered SrMnCrAsO.

Several different mechanisms of magnetoresistance (MR) have been observed in 1111 LnMnAsOF oxypnictides (Ln = lanthanide) as a result of magnetic coupling between the Mn and Ln. Such phases also exhibit interesting magnetic phase transitions upon cooling. SrMnCrAsO has been synthesized to investigate if it is possible to observe MR and/or magnetic phase transitions as a result of magnetic coupling between the Mn and Cr.
