Direct and Indirect measurements of the magnetic and magnetocaloric properties of Ni0.895Cr0.105MnGe1.05 melt-spun ribbons in high magnetic fields
Aryal, Anil (2019-10-15)We report the magnetic and magnetocaloric properties of rapidly solidified Ni0.895Cr0.105MnGe1.05 melt-spun ribbons studied by both direct (adiabatic temperature change) and indirect (isothermal magnetic entropy change) ... -
Enhanced refrigerant capacity and Curie temperature of amorphous Gd60Fe20Al20 microwires
Duc, N.T.M. (2019-10-30)Gd60Fe20Al20 microwires with an average diameter of ∼44 μm were fabricated by the melt-extraction method. XRD, TEM and HRTEM confirmed the amorphous nature of the microwires. The dimensional and chemical uniformity of the ... -
In-plane anisotropy in BSCCO superconducting tapes: transport and magnetometric criteria
Sánchez Valdés, César Fidel; García-Gordillo, A.S.; Sánchez Llamazares, J.L.; Altshuler, E. (2020-07-01)Here, the anisotropy between the longitudinal and transverse directions of multi-filamentary tapes (“in plane" anisotropy) is studied by transport and magnetization measurements. By minimally manipulating experimental data, ... -
Influence of γ phase on the magnetostructural transition and magnetocaloric properties in Ni38Co12Mn41Sn9 melt-spun ribbons
Sánchez Valdés, César Fidel; Chen, F.; Sánchez Llamazares, J.L.; Müllner, P.; Tong, Y.X.; Li, L. (2023-06-05)In the present work, Ni38Co12Mn41Sn9 melt-spun ribbons were annealed under different conditions to make samples free of secondary γ phase precipitates or get them with various average grain sizes. A comparative study was ... -
Magnetic properties of GaAs:Mn self-assembled nanostructures grown at relatively high-temperature by Molecular Beam Epitaxy
