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

Experiments on three double-layer (n=2) Ruddlesden-Popper (RP) systems are reported. Doping Sr1.8La1.2Mn2O7 (T-c = 126 K) with Nd to form Sr1.8La1.2-xNdxMn2O7 leads to a reduction in Curie temperature for low doping levels (x = 0.2), and to behavior

Neutron powder diffraction techniques have been used to refine the crystal and magnetic structures of the Ruddlesden Popper (RP) compounds Sr2-xNd1+xMn2O7 (x=0.0, 0.1), which show colossal magnetoresistance below 100 K. Samples of both compositions h

We present the results of a combined magnetization, muon-spin rotation, transport and magnetotransport study of the n = 3 Ruddlesden-Popper (RP) compound Ca4Mn3O10. This compound adopts a layered structure in which groups of three perovskite layers a

Zero field muon spin relaxation (μSR) has been used to study the magnetic properties of n=2 Ruddlesden-Popper phases Sr2RMn2O7, where R = Pr, Nd, Sm, Eu, Gd, Tb, Dy, and Ho. The results show that the size of the lanthanide ion is crucial in determin

Polycrystalline samples of the T′-phases R2Cu1-xPdxO4 (R=Nd, Sm, Eu, Gd; 0≤x≤0.2) have been characterized by x-ray powder diffraction (XRPD) and magnetometry. Doping with diamagnetic Pd induces orthorhombic symmetry and hence weak ferromagnetis
