Title: Magnetic properties of the rare-earth silicide Ho{sub 5}Si{sub 3}

Abstract

Despite their simple chemical formula and hexagonal structure, the magnetic and electrical properties of the family of rare-earth silicides R{sub 5}Si{sub 3} have not been systematically investigated. To begin our systematic study of this system, we have synthesized Ho{sub 5}Si{sub 3} and completed magnetic and resistivity measurements on this sample. AC susceptibility measurements show Ho{sub 5}Si{sub 3} to have {mu}{sub eff}=10.5{mu}{sub B}/Ho atom and {theta}=16.5 K. Magnetic measurements indicate that Ho{sub 5}Si{sub 3} undergoes two transitions at low temperatures, the first at 24 K is an antiferromagnetic transition, while the second, at about 8 K, is ferromagnetic. Low temperature measurements as a function of field reveal a metamagnetic transition at H{sub c}=2.2 T. The behavior of this sample is consistent with the complicated low temperature ordering found in other members of this series. (c) 2000 American Institute of Physics.
