Gadolinium is a nearly ideal soft-magnetic material. However, one cannot take advantage of its properties at temperatures higher than the room temperature where Gd loses ferromagnetic ordering. By using high-purity bulk samples with grains ~200 nm in size, we present proof-of-concept measurements an increased Curie point (TC) and spontaneous magnetization due to hydrogenation. From first-principles explain increase TC pure addition hydrogen. We show that interplay characteristic features...

High-purity Gd prepared by distillation is a structurally inhomogeneous system consisting of needle-shaped crystals cross section 0.5–2.5 μm with near-c-axis orientation embedded in matrix nanosized (30–100 nm) grains. By measuring the magnetocaloric effect (MCE) directly, we find that MCE values differ markedly for plate-shaped samples cut out distillate along and perpendicular to crystals. The small controlled amounts impurity (hydrogen) on properties distilled further studied. We observe...
The magnetic, magnetocaloric, and magnetoelastic properties of TbxDyyRz(Co,Fe)2 (R = Ho, Er; x + y z 1) single-phase alloys prepared by arc melting were investigated. high-purity samples with various compositions used for the study, a comprehensive investigation was performed. measurements magnetocaloric effect (MCE) carried out direct method; magnetostriction determined using strain-gauge technique. In vicinity magnetic phase transition, an abrupt change magnetization, large MCE, maxima...
An investigation of the Y2Fe17 compound belonging to class intermetallic alloys rare-earth and 3d-transition metals is presented. The magnetization, magnetostriction, thermal expansion single crystal were studied. forced magnetostriction constants investigated in temperature range magnetic ordering close room temperature. giant field induced volume was discovered region up 1.2 T. contributions both anisotropic single-ion isotropic pair exchange interactions determined. experimental results...
The magnetocaloric effect (MCE) and magnetoelastic (ME) anomalies at the magnetic phase transitions in (Tb0.45Dy0.55)1-xErxCo2 compounds (0.1 ≤ x 0.3) are studied. For synthesized with use of high-pure rare-earth metals, measurements MCE performed by a direct method study magnetostriction thermal expansion strain-gauge technique carried out. Large maximum observed vicinity studied compounds, which can be considered as potential materials for refrigeration. It is shown that energy...
Intermetallic compounds (Tb0.45Dy0.55)1−xErxCo2 (x = 0.1; 0.2) were synthesized using high purity rare-earth metals. Multicomponent compositions with compensated magnetic anisotropy (MA) chosen respect to theoretical predictions based upon the single-ion MA model. Magnetostriction was measured in fields up 10 T within temperature range of 1.5–200 K by means strain gauges. In vicinity phase transitions (160–170 K), giant volume magnetostriction (∼2×10−3 T) provided band magnetism a Co...
