A Dy-based bulk metallic glass with high thermal stability and excellent magnetocaloric properties

Magnetocaloric Effect in Uncoated Gd55Al20Co25 Amorphous Wires

“…Moreover, the series of refrigerants with first-order magnetic transition (FOMT) such as La(Fe,Si) [3] , Gd(GeSi) [4] and MnFePAs [5] alloys and with second-order magnetic transition (SOMT) e.g. pure Gd [6] , Gd-based [7] and Dy-based [8] alloys are developed for MR which applied in liquid nitrogen or room temperatures.…”

“…Gd is a unique member of the lanthanide series with large magnetic moment and its ground-state electronic configuration is 4f [7] (5d6s) [3][4][5][6][7][8][9] . In contrast to other rare earth metals, Gd has no orbital momentum, leading to a relatively small magnetocrystalline anisotropy and a wide composition range which is possible by alloying predominantly magnetic 3d transition elements 10 .…”

Unconventional elastic properties, deformation behavior and fracture characteristics of newly developed rare earth bulk metallic glasses

“…Owing to the aforementioned properties, RE-BMGs have been suggested as potential candidates for applications such as phase change erasable optical storage media [23], microdevice manufacture [24] or as matrices in composites suitable for various functional purposes. Remarkably, some rare earth BMGs also exhibit interesting magnetic properties [25] and low-temperature superconductivity [26]. It should be noted that while the thermal and elastic properties of these alloys have been investigated to some extent, much less attention has been paid to their deformation behavior and, in particular, to their fracture characteristics.…”

The Structural, Magnetic, and Magnetocaloric Properties of La1−x Ag x MnO 3 (0.05 ≤ x ≤ 0.25)

“…Magnetic cooling systems have high efficiency and are used in scientific and technological purposes at very low temperatures below room temperature. There has been an increase in research on the magnetocaloric effect (MCE) of manganitebased materials, due to the possibility of applying this effect for magnetic refrigeration close to room temperature [1][2][3][4][5].…”
