Effect of "dipolar-biasing" on the tunability of tunneling magnetoresistance in transition metal oxide systems

P. Anil Kumar, D. D. Sarma

We observe an unusual tunneling magnetoresistance (TMR) phenomenon in a composite of La $_{2/3}$ Sr $_{1/3}$ MnO $_{3}$ with CoFe $_{2}$ O $_{4}$ where the TMR versus applied magnetic fiel…

Revisiting Goodenough-Kanamori rules in a new series of double perovskites LaSr $_{1 - x}$ Ca $_{x}$ NiReO $_{6}$

Somnath Jana, Payel Aich, P. Anil Kumar +8

The magnetic ground state in highly ordered double perovskites LaSr $_{1 - x}$ Ca $_{x}$ NiReO $_{6}$ ( $x$ = 0.0, 0.5, 1.0) were studied in view of the Goodenough-Kanamori rules of superexcha…

Preparation, structural, dielectric and magnetic properties of LaFeO3-PbTiO3 solid solutions

S. A. Ivanov, R. Tellgren, F. Porcher +7

Solid solutions of (1-x)LaFeO3-(x)PbTiO3 (0<x<1) have been prepared by conventional solid-state reaction. These complex perovskites have been studied by means of X-ray (XRPD) and n…

Re-entrant superspin glass phase in La $_{0.82}$ Ca $_{0.18}$ MnO $_{3}$ ferromagnetic insulator

P. Anil Kumar, R. Mathieu, P. Nordblad +4

We report results of magnetization and ac susceptibility measurements down to very low fields on a single crystal of the perovskite manganite, La $_{0.82}$ Ca $_{0.18}$ MnO $_{3}$ . This c…

Temperature evolution of structural and magnetic properties of stoichiometric LiCu2O2: correlation of thermal expansion coefficient and magnetic order

S. A. Ivanov, P. Anil Kumar, R. Mathieu +3

Temperature-dependent crystallographic and magnetic studies on stoichiometric single crystals of LiCu2O2 are reported. The magnetic properties are similar to earlier findings demon…

Intertwined Magnetic Sub-Lattices in the Double Perovskite Compound LaSrNiReO6

Ola Kenji Forslund, Konstantinos Papadopoulos, Elisabetta Noccerino +13

We report a muon spin rotation ( $I^¼^{+}$ SR) study of the magnetic properties of the double perovskite compound LaSrNiReO $_{6}$ . Using the unique length and time scales of the $Î¼^{…
