6 Nov 2003 | Journal: | Journal of Low Temperature Physics 134, 1055 (2004) DOI: 10.1023/B:JOLT.0000016729.99257.25 | Subject: | Materials Science | cond-mat.mtrl-sci | Abstract: | We report measurements of the low temperature (T = 0.5 K) oscillatory magnetization in a high-density array of 50 micron diameter wires of polycrystalline Bi utilizing a high sensitivity silicon cantilever magnetometer. We find that the magnetic response is strongly anisotropic, being much larger for magnetic field perpendicular than for fields parallel to the wire-axis. We argue that this is a geometric effect caused by the large aspect ratio of the individual microwires in the array. The magnetic response of the microwires is dominated by the light electrons due to the larger cyclotron orbits in comparison with the heavier holes. We find that de Haas - van Alphen oscillations are easily resolved, and discuss the application of this technique to the study of Bi nanowire arrays. | Source: | arXiv, cond-mat/0311129 | Services: | Forum | Review | PDF | Favorites |
