Effect of reduced local lattice disorder on the magnetic properties of B-site substituted La0.8Sr0.2MnO3
Sagar Ghorai, Sergey A. Ivanov, Ridha Skini +2
Disorder induced by chemical inhomogeneity and Jahn-Teller (JT) distortions is often observed in mixed valence perovskite manganites. The main reasons for the evolution of this dis…
Evolution of Griffiths Phase and Critical Behaviour of La1-xPbxMnO3+-y Solid Solutions
Sagar Ghorai, Sergey A. Ivanov, Ridha Skini +1
Polycrystalline La1-xPbxMnO3+-y (x = 0.3, 0.35, 0.4) solid solutions were prepared by solid state reaction method and their magnetic properties have been investigated. Rietveld ref…
Enhancement of antiferromagnetic interaction and transition temperature in M3TeO6 systems (M = Mn, Co, Ni, Cu)
R. Mathieu, S. A. Ivanov, P. Nordblad +1
Several M3 TeO6 (M = Mn, Co, Ni, Cu) oxides order antiferromagnetically at low temperatures (near or below 60 K), while displaying interesting dielectric properties at high tempera…
MnFeSbO: a ferrimagnetic ilmenite and an antiferromagnetic perovskite
R. Mathieu, S. A. Ivanov, I. V. Solovyev +4
Due of its polymorphism, MnFeSbO can be synthesized at high pressures and temperatures as a ferrimagnetic ilmenite or an antiferromagnetic perovskite. The structural phase…
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…
First-order multi-k phase transitions and magnetoelectric effects in multiferroic Co3TeO6
Pierre Tolédano, Vera Carolus, Matthias Hudl +4
A theoretical description of the sequence of magnetic phases in Co3TeO6 is presented. The strongly first-order character of the transition to the commensurate multiferroic ground s…
