Optimising microstructural characterisation of white-matter phantoms: impact of gradient waveform modulation on Non-uniform Oscillating Gradient Spin-Echo sequences
Melisa L Gimenez, Pablo Jimenez, Leonardo A Pedraza Perez +3
Changes in the nervous system due to neurological diseases take place at very small spatial scales, on the order of the micro and nanometers. Developing non-invasive imaging method…
Strong magnetoelastic effect in CeCoFeSi as Néel order is suppressed
V. F. Correa, A. G. Villagrán Asiares, D. Betancourth +8
A very strong magnetoelastic effect in the CeCoFeSi alloys is reported. The strength of the magnetostrictive effect can be tuned upon changing . The moderate low-t…
Magnetostriction Reveals Orthorhombic Distortion in Tetrahedral Gd-compounds
Diana Betancourth, Victor F. Correa, Jorge I. Facio +5
We report detailed thermal expansion and magnetostriction experiments on GdCoIn and GdRhIn single crystal samples that show a sudden change in the dilation at a field B$^\a…
Antiferromagnetism weakening with Y-substitution in the TbRhIn intermetallic system
R. P. Amaral, R. Lora-Serrano, D. J. Garcia +8
We report measurements of the temperature dependence specific heat, magnetic susceptibility in single crystals of the series of intermetallic compounds TbYRhIn (nom…
Remarkable magnetostructural coupling around the magnetic transition in CeCoFeSi
V. F. Correa, D. Betancourth, J. G. Sereni +2
We report a detailed study of the magnetic properties of CeCoFeSi under high magnetic fields (up to 16 Tesla) measuring different physical properties such as spec…
Lattice specific heat for the RMIn (R = Gd, La, Y, M = Co, Rh) compounds: non-magnetic contribution subtraction
Jorge I. Facio, D. Betancourth, N. R. Cejas Bolecek +6
We analyze theoretically a common experimental process used to obtain the magnetic contribution to the specific heat of a given magnetic material. In the procedure, the specific he…
Why the Co-based 115 compounds are different?: The case study of GdMIn (M=Co, Rh, Ir)
Jorge I. Facio, D. Betancourth, Pablo Pedrazzini +4
The discovery in 2001 of superconductivity in some heavy fermion compounds of the RMIn (R=4f or 5f elements, M=Co, Rh, Ir) family, has triggered enormous amount of research poi…
Evidence of a small crystal field anisotropy in GdCoIn
Diana Betancourth, Victor F. Correa, Daniel J. García
We investigate the effects of an applied magnetic field on the magnetic properties of the antiferromagnet GdCoIn. The prominent anisotropy observed in the susceptibility below…
Low-temperature physical properties of GdCoIn
D. Betancourth, J. I. Facio, P. Pedrazzini +6
A comprehensive experimental and theoretical study of the low temperature properties of GdCoIn was performed. Specific heat, thermal expansion, magnetization and electrical res…
From magnetic to Fermi Liquid behavior in CeCo{1-x}Fe{x}Si alloys
J. G. Sereni, M. Gómez Berisso, D. Betancourth +3
Structural, magnetic and thermal measurements performed on CeCo{1-x}Fe{x}Si alloys are reported. Three regions can be recognized: i) Co-rich (x < 0.20) with a decreasing long range…
