Abstract:
The Curie temperature (T) and magnetic entropy change (-ΔS), and their relationship to the alloy composition of Tb-Co metallic glasses, were studied systematically in this paper. It was found that, in contrast to the situation in amorphous Gd-Co ribbons, the dependence of Tc on Tb content and the maximum -ΔS vs. T -2/3 plots in Tb-Co binary amorphous alloys do not follow a linear relationship, both of which are supposed to be closely related to the non-linear compositional dependence of Tb-Co interaction due to the existence of orbital momentum in Tb.

When an ideal gas expands isothermally, the disorder in the gas increases. From the molecular perspective, the gas molecules have more volume to move around in.
Consider an infinitesimal step in the expansion, which...
Magnetic Susceptibility and Permeability
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...
