In the isostructural integralvalent LaT 2 P 2 compounds similar phase transitions of second (T=Fe) and first order (T=Co) occur as a function of pressure indicating that the T element essentially determines the nature of the phase transition. The different types of phase transitions are ...
Using a range of numerical criteria, we present strong evidence that the so-called A-C transition is first order, while the B-C transition is second order. The presence of a second-order transition may be related to an ultraviolet fixed point of quantum gravity and thus provide the key to...
The magnetization can vanish either by a first order phase transition (class-I superconductors), or by a second order (class-II). The boundary S I–II , which separates two regions (I and II) on the plane of variables ( D , ), is found. The boundary ζ ( D , ) of the region,...

The phase transition is first-order when the many-body interaction is long-ranged, but second-order when the many-body interaction is short-ranged. The change in the order of the phase transition is related to a crossing of the stability limits of the diatomic structure with respect to ...

For those undergoing first-order phase transition (FOPT), they usually exhibit large ΔSiso values, but their accompanying thermal and magnetic hystereses can affect their cyclicality. On the other hand, for those exhibiting second-order phase transition (SOPT), while they exhibit no hysteresis,...
The types of magnetic phase transitions (first- or second-order) in (R-Y)Co2 and RCo2 (R=heavy rare-earth element) under high pressure are studied by making use of a phenomenological model where the coexistence of localised moments on R atoms and itinerant d electrons is assumed. The conc...
