Magnetic behavior and magnetocaloric effect of neodymium-based amorphous alloy

Reduced magnetization M(T)/M(o) much broader than in the case of FeB and versus reduced temperature T/Tc for an FeNiB amorphous alloys.. A fit of the exPg applied field of

The magnetic properties of Tb,,Ag,, have been measurements have been done with the apparatus found to exhibit, at low temperature, a high coercive and

However, FOMTs occur in a narrow temperature window and are often accompanied with some non-desirable effects such as: irreversibility of the effect, poor mechanical

Thus, the analysis of the critical behavior in the vicinity of the magnetic phase transi- tion is a powerful tool to investigate in details the mechanisms of the magnetic

The magnetocaloric effect (MCE) can be related to the magnetic properties of the material through the thermo- dynamics Maxwell’s relations, and it has been calculated in terms

Using the recently proposed criterion of field depen- dence of the magnetocaloric effect, we show that the ferromagnetic transition is more likely to be of second order, which is
