Abstract

X-ray thermal expansion, magnetic and electrical resistivity measurements of the pseudo-binary Ho1-xYxCo3 system with PuNi3 -type structure have been performed in a wide temperature range. Temperature-induced itinerant-electron metamagnetism has been observed in the concentration range 0.0 [less-than-or-equals, slant] x [less-than-or-equals, slant] 0.4 where the Co sublattice is in the strong ferromagnetic state at low temperatures. The transition was found to be sharper in the diluted compounds with a lower value of the transition temperature, which is in accordance with the nature of the observed effect. The temperatures of the spin-reorientation transition have been determined from low-field magnetisation measurements and the magnetic phase diagram of this system has been constructed.
