Unusual effects of manual grinding and subsequent annealing process observed in Gd5.09Ge2.03Si1.88 compound
A. M. G. Carvalho, C. S. Alves, P. V. Trevizoli +3
The Gd5.09Ge2.03Si1.88 compound, as well as other magnetocaloric materials, certainly will not be used in their un-manufactured as-cast condition in future magnetic refrigeration a…
Active control of thermomagnetic avalanches in superconducting Nb films with tunable anisotropy
D. Carmo, F. Colauto, A. M. H. de Andrade +4
Active triggering and manipulation of ultrafast flux dynamics in superconductors are demonstrated in films of Nb. Controlled amounts of magnetic flux were injected from a point alo…
Size-dependent bandgap and particle size distribution of colloidal semiconductor nanocrystals
Diego Lourençoni Ferreira, J. C. L. Sousa, R. N. Maronesi +4
A new analytical expression for the size-dependent bandgap of colloidal semiconductor nanocrystals is proposed within the framework of the finite-depth square-well effective mass a…
Giant barocaloric effects in natural rubber: A relevant step toward solid-state cooling
N. M. Bom, W. Imamura, E. O. Usuda +2
Solid-state cooling based on i-caloric effects has shown to be a promising alternative to the conventional refrigeration devices. Only very recently, the research on barocaloric ma…
Pressure-tuning of bond-directional exchange interactions and magnetic frustration in hyperhoneycomb iridate -
L. S. I. Veiga, M. Etter, K. Glazyrin +14
We explore the response of Ir orbitals to pressure in -, a hyperhoneycomb iridate in proximity to a Kitaev quantum spin liquid (QSL) ground state. X-ray…
Low-complexity Distributed Tomographic Backprojection for large datasets
Gilberto Martinez, Janito V. Ferreira Filho, Eduardo X. Miqueles
In this manuscript we present a fast GPU implementation for tomographic reconstruction of large datasets using data obtained at the Brazilian synchrotron light source. The algorith…
Realization of Rectangular Artificial Spin Ice and Direct Observation of High Energy Topology
I. R. B. Ribeiro, F. S. Nascimento, S. O. Ferreira +7
In this letter, we have constructed and experimentally investigated frustrated arrays of dipoles forming two-dimensional artificial spin ices with different lattice parameters (rec…
Giant room-temperature barocaloric effects in PDMS rubber at low pressures
A. M. G. Carvalho, W. Imamura, E. O. Usuda +1
The barocaloric effect is still an incipient scientific topic, but it has been attracting an increasing attention in the last years due to the promising perspectives for its applic…
Large barocaloric effects at low pressures in natural rubber
Érik O. Usuda, Nicolau M. Bom, Alexandre Magnus G. Carvalho
Barocaloric effect in vulcanized natural rubber (V-NR) has been investigated. Direct measurements of the temperature change (ΔT) around room temperature (283-333 K) resulted in lar…
