We report on a quantum critical behavior in the quasi-1D spin-1/2 zigzag frustrated chain antiferromagnet CaCoV_{2}O_{7}, induced by an applied magnetic field. Below T_{N}=3.3 K our zero-field neutron diffraction studies revealed the up-up-down-down

Magnetic refrigeration is a highly active field of research. The recent studies in materials and methods for hydrogen liquefaction and innovative techniques based on multicaloric materials have significantly expanded the scope of the field. For this

We present the effect of substitution-induced pressure on the reversibility of the magnetocaloric effect (MCE) in ${\mathrm{Ni}}_{2}{\mathrm{Cr}}_{x}{\mathrm{Mn}}_{1.4\ensuremath{-}x}{\mathrm{In}}_{0.6}$ ($x=0.1$, 0.2, 0.3) alloys, through characteri

Hydrogen has the largest gravimetric energy density among all chemical fuels. At the same time, the density of gaseous ${\mathrm{H}}_{2}$ is extremely low, which makes its compression to high pressures, liquefaction, or solid-state storage necessary

Magnetocaloric effect (MCE) in pulsed magnetic fields up to 50 T was directly studied in alloy Fe49Rh51. An inverse MCE ΔT ≈ –8 K is observed at different initial temperatures around the metamagnetic phase transition upon field rising to 20 T; f

Composite quantum materials are the ideal examples of multifunctional systems which simultaneously host more than one novel quantum phenomenon in physics. Here, we present a combined theoretical and experimental study to demonstrate the presence of a

Numerous materials feature unexplained phases with invisible or hidden order of electronic origin. A particularly mysterious case is that of ${\mathrm{Tb}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$, which avoids magnetic order to the lowest temperatures,

Ni-Mn-In magnetic shape-memory Heusler alloys exhibit generally a large thermal hysteresis at their first-order martensitic phase transition which hinder a technological application in magnetic refrigeration. By optimizing the Cu content in Ni$_2$Cu$
