The Co-Ir orbital hybridization in LaCaCoIrO double perovskite
L. Bufaiçal, L. S. I. Veiga, J. R. L. Mardegan +5
Here, we report on the structural, electronic, and magnetic properties of a polycrystalline sample of the LaCaCoIrO double-perovskite investigated by means of synchrotron x-ray…
The effect of structural and magnetic disorder on the 3-5 exchange interactions of LaCaCoIrO
L. Bufaiçal, E. Sadrollahi, F. J. Litterst +7
The delicate balance between spin-orbit coupling, Coulomb repulsion and crystalline electric field interactions observed in Ir-based oxides is usually manifested as exotic magnetic…
Possible quantum fluctuations in the vicinity of the quantum critical point of revealed by high-energy X-ray diffraction study
L. S. I. Veiga, J. R. L. Mardegan, M. v. Zimmermann +7
We explore the evolution of the structural phase transition of , a model system to study the interplay between structural quantum criticality and superc…
The zero-field-cooled exchange bias effect in phase-segregated LaACoMnO (A = Ba, Ca, Sr; x = 0, 0.5)
L. T. Coutrim, D. Rigitano, C. Macchiutti +9
In the zero-field-cooled exchange bias (ZEB) effect the unidirectional magnetic anisotropy is set at low temperatures even when the system is cooled in the absence of external magn…
Magnon excitations and quantum critical behavior of the ferromagnet URuGe
M. P. Nascimento, M. A. Continentino, A. López +8
We present an extensive study of the ferromagnetic heavy fermion compound URuGe. Measurements of electrical resistivity, specific heat and magnetic properties show that…
Pressure effects on the structural and superconducting transitions in La3Co4Sn13
L. Mendonça-Ferreira, F. B. Carneiro, M. B. Fontes +8
La3Co4Sn13 is a superconducting material with transition temperature at Tc = 2.70 K, which presents a superlattice structural transition at T* ~ 150 K, a common feature for this cl…
