Magnetic and Transport Properties of Tm2Co7B3 Compound
Magnetic and transport properties of Tm2Co7B3 compound have been studied. This compound crystallizes in the hexagonal Ce2Co7B3 type structure. The coercivity (Hc) of the compound was determined from hysteresis measurements in fields up to 4 T. The temperature dependence of coercivity has been explained by a thermally activated process of domain wall motion. The resistivity at low temperatures shows a T2 dependence. At higher temperatures the resistivity is not a linear function of temperature, which indicates an electron-phonon interaction in the presence of a small s-d scattering.
Abstract This study was undertaken to investigate the interaction of aqueous protactinium with various monobasic acids at an ionic strength and acidity of 1·00. This present work adds to the existing information on the anionic complexing of protactinium which was collected at an ionic strength of 3 and an acidity of 1–3 N. The solvent extraction method involves the measurement of the distribution of protactinium (Pa-233) between various aqueous solutions and a benzene phase containing the bidentate chelating agent, thenoyltrifluoroacetone (TTA).
