“…1 ' 5-7 Direct confirmation of this hypothesis has not been obtained from magnetic-susceptibility, 4 ' 8-10 neutron-diffraction, 11 or specific-heat 12 measurements. Those property measurements which have indicated a magnetic transition are radiation damage, [13][14][15][16] Hall effect, 3 -17 thermal expansion, 18 * 19 and thermoelectric power. 6 ' 19 The latter set of properties give indirect indications of magnetism by means of similar behavior for known magnetic metals, e.g., a manganese and the rare earths.…”

Transverse magnetoresistivity measurements have been made on pure, polycrystalline a and 0 plutonium. The magnetoresistivity of both phases is negative at 5°K and low applied fields, and becomes positive at fields greater than 2000 G. The negative effect decreases with increasing temperature and is not dependent on sample texture. The higher-field results follow the H 2 dependence found in f 'normal'' metals. It is concluded that the negative effect is due to magnetic ordering, which results from s-f exchange, and the Neel temperatures are near 20-30°K for both phases. The high-field data are consistent with earlier models in which the electrical conductivity is dominated by a small number of holes in the 7s band.

“…With c = Ap/Ap-p and the resistivity increase per 100 at.% Frenkel pairs App= 2.5X10"" 4 Here P is the production rate of Frenkel pairs which also includes the fraction y of unstable interstitials originally placed within the recombination volume V s around their corresponding vacancies. The parameters P = 1.34X 10"* 26 fi cm/(r/cm 2 ), r=0.1, and V s = 200 atomic volumina were obtained by fitting formula (3) to the experimental data (solid curve in Fig.…”
