Magnetic and Electronic Properties of Double Perovskite Sr 2-x La x VMoO 6
The magnetic and electronic properties of double perovskite Sr 2- x La x VMoO 6 ( x = 0.9–1.2) polycrystalline bulk samples have been investigated. Magnetization and electrical resistivity measurements indicate that Sr 2- x La x VMoO 6 is an antiferromagnetic metal with an antiferromagnetic transiti...
