Magnetic properties of the Anderson model: a local moment approach | | D. E. Logan
; N. L. Dickens

13 Jul 2001 | | Journal: | D. E. Logan and N. L. Dickens 2001 Europhys. Lett. 54 227 | | Subject: | Strongly Correlated Electrons | cond-mat.str-el | | Abstract: | We develop a local moment approach to static properties of the symmetric Anderson model in the presence of a magnetic field, focussing in particular on the strong coupling Kondo regime. The approach is innately simple and physically transparent; but is found to give good agreement, for essentially all field strengths, with exact results for the Wilson ratio, impurity magnetization, spin susceptibility and related properties. | | Source: | arXiv, cond-mat/0107290 | | Services: | Forum | Review | PDF | Favorites | |
