چکیده

High-purity samples of potassium trifluoroargentate(II), KAgF3, have been obtained via a novel synthetic pathway. This compound is found to exhibit an order-disorder phase transition around 230 K. Susceptibility measurements indicate that KAgF3 exhibits strong antiferromagnetic (AFM) coupling reminiscent of that found in copper(II) oxides.

Electronic Properties of Fluoride and Half–fluoride Superlattices KZnF3/KAgF3 and SrTiO3/KAgF3

We present the formation of cupratelike electronic structures in KAgF3-related superlattices resulted from the confinement together with structural chemical modification by using the generalized gradient approximation augmented with maximally localized Wannier functions analysis. Strong antiferromagnetic coupling found in bulk KAgF3 is held in purely-fluoride KZnF3/KAgF3. Under 4% in-plane comp...

Ferromagnetic-antiferromagnetic transition in „La-R...4Ba2Cu2O10

Cuprate La-R 4Ba2Cu2O10 shows ferromagnetic to antiferromagnetic phase transition by replacing La ions with rare earth R=Nd, Sm, Eu, and Gd ions at low temperature. We propose that the transition is caused by a competition between antiferromagnetic superexchange interaction of Cu spins via La ions and ferromagnetic superexchange interaction due to Hund’s rule coupling of spins of holes on oxyge...

Temperature and frequency dependent giant magnetodielectric coupling in DyMn0.33Fe0.67O3

Perovskite DyMn0.33Fe0.67O3 experiences a paramagnetism-antiferromagnetism transition at 450K and spin reorientation at 290 K. Magnetodielectric properties were studied around the spin reorientation transition. Both giant positive and giant negative magnetodielectric coupling (MDC) were observed near room temperature. The MDC shows strong temperature and frequency dependence, and the sign chang...

Theoretical magnetochemistry of dinuclear manganese complexes: broken symmetry density functional theory investigation on the influence of bridging motifs on structure and magnetism.

A systematic study of the magnetic coupling in homovalent (III-III and IV-IV) and heterovalent (III-IV) manganese dimers as a function of the chemical identity and coordination mode of the bridging ligands is carried out with the aim of establishing a reference library of magnetostructural correlations. Emphasis is placed on rationalising the results through analysis of the superexchange pathwa...

Comparative studies on the room-temperature ferrielectric and ferrimagnetic Ni3TeO6-type A2FeMoO6 compounds (A = Sc, Lu)

First-principles calculations have been carried out to study the structural, electric, and magnetic properties of Ni3TeO6-type A2FeMoO6 compounds (A = Sc, Lu). Their electric and magnetic properties behave like room-temperature ferrielectric and ferrimagnetic insulators where polarization comes from the un-cancelled antiparallel dipoles of (A(1), Fe(3+)) and (A(2), Mo(3+)) ion groups, and magne...
