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 T_C=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.
