Colossal magnetoresistance in Sr2-xNd1+xMn2O7 (x=0.0,0.1)

Abstract:

Magnetization and magnetotransport measurements have been used to study the composition dependence of the electronic properties of the Ruddlesden-Popper phases Sr2NdMn2O7 and Sr1.9Nd1.1Mn2O7. Although their behaviour differs in detail, both compounds show a colossal magnetoresistance (CMR) effect (>10 000% in 14 T) in the temperature range 4.2 ≤ T/K ≤ 100. However, neither material shows a transition to a ferromagnetic state above 4.2 K, and both materials have higher resistivities (>10...
