Abstract

The magnetic and magnetocaloric properties of the RCo5 polycrystalline alloys (with R = Gd, Tb, Dy, and Ho) are studied experimentally in external magnetic fields of to 3 T. Magnetic measurements show that these compounds are characterized by low coercive force and are going to saturation in low magnetic fields. The magnetocaloric effect of the compounds under study is found to be observed in a wide temperature range, and the TbCo5, DyCo5, and HoCo5 intermetallic compounds exhibit several temperature ranges which are comparable in the value of the effect. The several ranges of the existence of MCE of these ferrimagnetic compounds are due to the series of magnetic phase transitions in them. [ABSTRACT FROM AUTHOR]

Abstract

Structural regularities of the transformation of PAN fibers into high-strength sp2-carbon fiber by high-temperature thermomechanical treatment were established using Raman spectroscopy and X-ray diffraction. Radial heterogeneity of the fiber structure was revealed and quantitatively characterized by Raman micro-mapping. [ABSTRACT FROM AUTHOR]

26. The Effect of Plastic Deformation on Magnetic and Magnetocaloric Properties of Gd90Ga10 Alloy

Author

Taskaev, Sergey V., Skokov, Konstantin P., Karpenkov, Dmitriy Yu., Khovaylo, Vladimir V., Ulyanov, Maxim N., Bataev, Dmitriy, Pellenen, Anatoliy, and Fazlitdinova, Alfiya G.

Abstract

In this work we report the results of experimental investigation of the magnetocaloric effect in Gd90Ga10 cold rolled ribbons. A moderate entropy change ΔS = 3.5 J/(kg·K) and magnetocaloric effect ΔT = 3.4K was observed for the as-cast materials in an external magnetic field of 2T which is less by 35% in comparison with the pure gadolinium metal. It was found that a significant (up to 70%) depression of magnetization and magnetocaloric properties developed in the course of plastic deformation can be completely restored by means of a high temperature heat treatment.
