Strong enhancement of superconductivity at high pressures within the charge-density-wave states of 2H-TaS 2 and 2H-TaSe 2
2016
We present measurements of the superconducting and charge density wave critical temperatures (Tc and TCDW) as a function of pressure in the transition metal dichalchogenides 2H-TaSe2 and 2H-TaS2. Resistance and susceptibility measurements show that Tc increases from temperatures below 1 K up to 8.5 K at 9.5 GPa in 2H-TaS2 and 8.2 K at 23 GPa in 2H-TaSe2. We observe a kink in the pressure dependence of TCDW at about 4 GPa that we attribute to the lock-in transition from incommensurate CDW to commensurate CDW. Above this pressure, the commensurate TCDW slowly decreases coexisting with superconductivity within our full pressure range.
Internal-strain mediated coupling between polar Bi and magnetic Mn ions in the defect-free quadruple-perovskite BiMn$_3$Mn$_4$O$_{12}$
2011
By means of neutron powder diffraction, we investigated the effect of the polar Bi$^{3+}$ ion on the magnetic ordering of the Mn$^{3+}$ ions in BiMn$_3$Mn$_4$O$_{12}$, the counterpart with \textit{quadruple} perovskite structure of the \textit{simple} perovskite BiMnO$_3$. The data are consistent with a \textit{noncentrosymmetric} spacegroup $Im$ which contrasts the \textit{centrosymmetric} one $I2/m$ previously reported for the isovalent and isomorphic compound LaMn$_3$Mn$_4$O$_{12}$, which gives evidence of a Bi$^{3+}$-induced polarization of the lattice. At low temperature, the two Mn$^{3+}$ sublattices of the $A'$ and $B$ sites order antiferromagnetically (AFM) in an independent manner …

Reflexiones a propósito de la protección de datos en el escenario global digital: El derecho de daños en la litigiosidad internacional
2021
La circulación internacional de datos personales constituye un sector pujante en la esfera socio-económica. En tales condiciones, ante la existencia de un tratamiento ilícito de aquellos, el agraviado está legitimado para exigir una indemnización por los daños y perjuicios que se hubieran podido originar en el marco transfronterizo. Tal situación plantea dos cuestiones fundamentales: por un lado, determinar el órgano jurisdiccional competente para conocer de un eventual litigio, y, por otro, precisar la Ley aplicable para resolver la controversia suscitada. En la presente investigación cabe destacar las significativas novedades que introduce el Reglamento (UE) 2016/679, de 27 de abril de 20…
Different approaches to marriage downgrading : from an anti-elusive measure to an antidiscriminatory claim
2021
The essay focuses on the different mechanisms of marriage downgrading. Given the principle of ?cross-border continuity? of statuses, limits to this continuity are sometimes admitted and they are placed through downgrading mechanisms. That can occour in the case of same-sex marriages transcription in a Member State which does not allow such marriages, but which does allow samesex registered partnerships. Downgrading mechanism has an anti-elusive function, but it is not without problems in terms of discrimination on the grounds of sexual orientation. A different approach is taken in the case of an opposite-sex couple requesting the downgrading of their marriage, celebrated before the Member S…
Anulación del privacy shield en las transferencias internacionales de datos : ¿presenciamos un desplazamiento fáctico de la responsabilidad?
2021
This study provides a comprehensive analysis of international transfers of personal data to third countries or international organizations due to new privacy regulation. More specifically, it analyzes the effects on this regulatory scheme of the annulment of the Privacy Shield in the transatlantic information movements between the European Union and the United States and how this implies, in fact, a transfer of responsibility to the controller
Pre-marital and pre-unional financial agreements and their circulation in the context of the new EU regulations 2016/1103 and 2016/1104
2021
Regulations (EU) 2016/1103 and 2016/1104 provide spouses and partners with the possibility to conclude agreements for the organization of their property regime but do not detail their content and structure. Moreover, while the possibility to conclude those agreements even prior to the marriage or the conclusion of a registered partnership is a valuable innovation in comparison with other European Regulations in family matters, some choices made by the European legislator on applicable law will likely be source of inconveniences. Furthermore, as for their recognition and enforcement in the participating Member States ? which will be based on the same rules enacted for decisions, authentic in…
Liquidación de la sociedad de gananciales: el caso de la adjudicación forzosa de participaciones sociales de carácter ganancial a un solo cónyuge. Co…
2021
In a liquidation of community property, the rules for the partition of the inheritance are of suppletive application. Therefore, the sentence opts for a criterion of flexible interpretation of those rules, whose application will be subject to the objective entity of the property in question. Accordingly, when the only property to be shared between the spouses is constituted by set of shares of common nature, taking into account the special circumstances of the case, such shares could be awarded to one of the spouses with the obligation to compensate the other in money, even if it requests the sale of the shares in the public auction. To this end, the request would have to impede the possibi…
