Enhanced weak superconductivity in trigonal -PtBi
J. Zabala, P. Pedrazzini, F. J. Castro +1
Electrical resistivity experiments show superconductivity at K in a high-quality single crystal of trigonal -PtBi, with an enhanced critical magnetic field $μ_0…
Low-temperature thermal expansion of the topological material candidates -PtBi and -BiPd
V. F. Correa, P. Pedrazzini, D. G. Franco +3
We report on the low-temperature ( 120 K) thermal expansion of the bismuth-based topological semimetal -PtBi and topological superconductor -BiPd candidates. The…
First-order phase transformation at constant volume: a continuous transition?
V. F. Correa, F. J. Castro
We describe a first-order phase transition of a simple system in a process where the volume is kept constant. We show that, unlike what happens when the pressure is constant, (i) t…
Minimal model for the magnetic phase diagram of CeTiScGe, GdFeCoSi, and related materials
William Gabriel Carreras Oropesa, Sergio Encina, Pablo Pedrazzini +5
We present a theoretical analysis of the magnetic phase diagram of CeTiScGe and GdFeCoSi as a function of the temperature and the Sc and Co concentratio…
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…
Introducing the Hamiltonian as a "thermodynamic" potential
Víctor F. Correa
A conceptually simple physical interpretation of a conserved Hamiltonian for a mechanical system with a time-dependent constraint is given. For the case of a bead on…
