Abstract
Copyright (c) 1997 Elsevier Science S.A. All rights reserved. The magnetic (magnetization and coercivity) and transport (electrical resistivity) properties of the Tm3Co11B4 compound have been studied. This compound crystallizes in the hexagonal Ce3Co11B4 type structure. Results show that the Tm3Co11B4 is a ferromagnet with TC=347 K and a compensation point equal to 125 K. The coercivity of the compound was determined from hysteresis measurements in fields up to 4 T. For the Tm3Co11B4 compound we have observed a large increase of coercivity at low temperatures, typically from 0.01 T at 295 K to 0.8 T at 30 K. The resistivity at low temperatures shows a T2 dependence, implying that electron-spin wave scattering is dominant in this temperature range.
