对填充的方角石化合物PrOs{sub 4}As{sub 12}的单晶进行磁化、比热和电阻率测量。比热测量表明,在10 K{le} T {le} 18 K温度下,电子比热系数{γ}{约}50-200 mJ/mol K{sup 2},在1.6 K温度下,电子比热系数{约}1 J/mol K{sup 2}。磁化、比热和电阻率测量显示,在低于{约}2.3 K的温度和低于{约}3 t的电场中,存在两个或可能三个有序相。低温相显示出反铁磁特性,而其他相的有序性质尚未确定。
Magnetization, specific heat, and electrical resistivity measurements were made on single crystals of the filled skutterudite compound PrOs{sub 4}As{sub 12}. Specific heat measurements indicate an electronic specific heat coefficient {gamma} {approx} 50-200 mJ/mol K{sup 2} at temperatures 10 K {le} T {le} 18 K, and {approx} 1 J/mol K{sup 2} for t {le} 1.6 K. Magnetization, specific heat, and electrical resistivity measurements reveal the presence of two, or possibly three, ordered phases at temperatures below {approx} 2.3 K and in fields below {approx} 3 T. The low temperature phase displays antiferromagnetic characteristics, while the nature of the ordering in the other phase(s) has yet to be determined.
