Magnetic susceptibility and electrical resistivity of electrotransport purified scandium single crystals from ≈ 1 to 300 k
Journal of Magnetism and Magnetic Materials(1983)
摘要
The magnetic susceptibility of electrotransport purified Sc single crystals was measured from 0.7 to 295 K. Both the easy (χa) and hard (χc) directions were measured using a microcomputer controlled Faraday apparatus. Above 50 K the present results agree with earlier work on a less pure sample, but below 50 K the present results are lower by as much as 4%. In addition the maximum at ≈ 30 K and the minimum at ≈ 6 K are much more pronounced in the purer material, and the susceptibility increases rapidly as the temperature approaches 0 K. Electrical resistivity measurements were made on the same single crystals from 1.6 to 300 K. The resistance ratios were 365 for the a-axis crystal and 274 for the c-axis crystal. At 300 K, ρa ≈ 2.5 ρc.
