Frustrated magnetism and caloric effects in Mn-based antiperovskite Nitrides : Ab Initio theory [PDF]
, 2017 We model changes of magnetic ordering in Mn-antiperovskite nitrides driven by biaxial lattice strain at zero and at finite temperature. We employ a non-collinear spin-polarised density functional theory to compare the response of the geometrically ...

Chemistry – A European Journal, Volume 31, Issue 60, October 27, 2025.The impact of X‐ray damage in chemical crystals was minimised by the introduction of area detectors in the late 20th‐century. Now, ever‐brighter X‐ray sources are re‐establishing X‐ray damage as a key challenge. This article reviews recent observations of X‐ray‐induced processes in chemical samples and discusses state‐of‐the‐art methodologies for their

Fantastic barocalorics and where to find them
Applied Physics Letters, 2021 Barocaloric materials have the potential to offer greener and more efficient alternatives to conventional refrigerants that exploit vapor compression for cooling and heating applications. The barocaloric effect, a temperature change in response to hydrostatic pressure, is widespread in materials; however, only in the last few years have giant and ...

Barocaloric effect in ferroelastic fluorides and oxyfluorides [PDF]
Ferroelectrics, 2016 Using the data about the temperature - pressure phase diagram and the phase transition entropy at ambient and high pressure, intensive and extensive barocaloric effects were analyzed in the region of single and successive order-disorder phase transitions in fluorides and oxyfluorides with the elpasolites-cryolite structure.

Numerical and thermal analysis of a caloric refrigeration device operating near room temperature
International Journal of Air-Conditioning and Refrigeration, 2023 The application of external stimuli such as the magnetic and electric field in magnetocaloric and electrocaloric materials, and stress and pressure in elastocaloric and barocaloric materials give rise to a new generation of a refrigeration technology ...

Ultrastable glasses portray similar behaviour to ordinary glasses at high pressure [PDF]
, 2016 Pressure experiments provide a unique opportunity to unravel new insights into glass-forming liquids by exploring its effect on the dynamics of viscous liquids and on the evolution of the glass transition temperature.

Stress-induced transformation in a Ni-Mn-In alloy and the concomitant change of resistivity [PDF]
, 2015 In this work, the influence of mechanical stress on magnetic properties and electric resistance of a Ni-Mn- In alloy was studied. It is shown that compression of Ni-Mn-In polycrystalline specimens brings about a stressinduced martensitic transformation ...

Step-like features on caloric effects of graphenes
, 2014 We considered a graphene nano-ribbon with a longitudinal electric field (along $x$ direction) and a transversal magnetic field (along $z$ direction), and then observe (i) the electrocaloric effect ruled by an applied magnetic field and (ii) the ...
