The magnetization M and electrical resistivity rho have been measured at 0 < or = H < or = 135 kG and 1.2 < or = T < or = 27 K for the transition metal hcp Zr containing Mn at concentrations 520 < or = c < or = 3100 ppm. The primary results are (a) the measurements confirm earlier indications that Mn displays a localized magnetic moment when in solution in hcp Zr and suggest a Kondo temperature T/sub K/ < 1.0 K; (b) both the high-H saturation magnetization and the low-H susceptibility show that the spin S associated with Mn in Zr is 2.0 +- 0.2; (c) the impurity magnetization ..delta..M equivalent M (alloy) -M (Zr) obeys the Blandin-Souletie-Tournier scaling ..delta..M/c = F (H/c, T/c), suggesting the dominance of a long-range oscillating Ruderman-Kittel-Kasuya-Yosida (RKKY-like moment-moment interaction, as appears to exist in the more widely investigated non-transition-metal--host spin glasses; (d) the behavior of the resistivity, susceptibility, and reversible magnetization indicates that spin-freezing temperatures T/sub 0/(c) (if such exist in Zr-Mn) are below the present 1.2-K temperature limit; (e) the high T > T/sub 0/, high H >> k/sub B/T/g..mu../sub B/, Larkin-Khmel'nitskii (LK) prediction ..delta..M (LK) = ..delta..M/sub s/(1 - H/sub 0//H) (..delta..M/sub s/ is the impurity saturation magnetization, H/sub 0/ proportional cV/sub 0/, V/sub 0/ is the RKKY coefficient) does not account for the (i) T-dependence of ..delta..M, (ii) relatively low fields 40 9 or approx. = H/sub s/ 9 or approx. = 130 kG (at 520 < or = c < or = 3100-ppm Mn) required for saturation of the impurity magnetization at 1.2 K; (f)
