Existence of inter coupled structural, electronic and magnetic states in Sm$ _{2} $NiMnO$ _{6} $ double perovskite

Autor: Majumder, S., Tripathi, M., de Souza, D. O., Sagdeo, A., Olivi, L., Singh, M. N., Pal, S., Choudhary, R. J., Phase, D. M.

Coupling between different interactions allows to control physical aspects in multifunctional materials by perturbing any of the degrees of freedom. Here, we aim to probe the correlation among structural, electronic and magnetic observables of Sm$ _{

Microscopic insights of magnetism in Sm$ _{2} $NiMnO$ _{6} $ double perovskite

Autor: Majumder, Supriyo, Tripathi, Malvika, Fischer, H. E., de Souza, D. O., Olivi, L., Sinha, A. K., Choudhary, R. J., Phase, D. M.

Publikováno v: Phys. Rev. B 105, 094425 1-13 (2022)

The functional characteristics of double perovskites with unique ferromagnetic-insulator ground state have been controversial due to the unavoidable presence of anti-site disorders (ASDs). Here, we aim to investigate the origin of magnetic ordering o

Mapping the magnetic state as a function of anti-site disorder in Sm$ _{2} $NiMnO$ _{6} $ double perovskite thin films

Autor: Majumder, S., Tripathi, M., Raghunathan, R., Rajput, P., Jha, S. N., de Souza, D. O., Olivi, L., Chowdhury, S., Choudhary, R. J., Phase, D. M.

Publikováno v: Physical Review B 105(2):024408 1-15 (2022)

The predictability of any characteristic functional aspect in a double perovskite system has always been compromised by its strong dependence over the inevitably present anti-site disorders (ASD). Here, we aim to precisely map the quantitative and qu

Multilayers black phosphorus: from tight-binding to continuum description

Autor: de Souza, D. J. P., de Castro, L. V., da Costa, D. R., Pereira Jr., J. Milton, Low, Tony

Publikováno v: Phys. Rev. B 96, 155427 (2017)

We investigate the electronic properties of $N$-layer black phosphorus by means of an analytical method based on a recently proposed tight-binding Hamiltonian involving $14$ hopping parameters. The method provides simple and accurate general expressi

Wavelet Analysis as an Information Processing Technique

Autor: de Oliveira, H. M., de Souza, D. F.

A new interpretation for the wavelet analysis is reported, which can is viewed as an information processing technique. It was recently proposed that every basic wavelet could be associated with a proper probability density, allowing defining the entr
