Kurzbeschreibung (Abstract)
A B-site disordered double perovskite La2CrNiO6 is synthesized by citrate-gel combustion method. The material is showing an orthorhombic Pbnm crystal structure which doesn't change upon cooling to 15 K and with an applied field of 50 kOe. Upon cooling from room-temperature to 15 K, a nearly linear dependence in the volume of the crystal structure with temperature is observed until 100 K, which is around the ferrimagnetic transition temperature of the material. The disordered Cr and Mn introduced inhomogeneous magnetic interactions, leading to Griffiths-like phase (GP) and spin glass state in the material. The material shows an exchange bias effect, owing to the GP and spin glass state. Mott's variable range hopping is the conduction mechanism of the insulating disordered double perovskite La2CrNiO6.
