21 Feb 2004 | | Journal: | J. Phys.: Condens. Matter 16 (2004) L167-L172 DOI: 10.1088/0953-8984/16/12/L02 | | Subject: | Strongly Correlated Electrons | cond-mat.str-el | | Abstract: | Local-susceptibility measurements via the NMR shifts of $^{31}$P and $^{51}$V nuclei in the high-pressure phase of (VO)$_{2}$P$_{2}$O$_{7}$ confirmed the existence of a unique alternating antiferromagnetic chain with a zero-field spin gap of 34 K. The $^{31}$P nuclear spin-lattice relaxation rate scales with the uniform spin susceptibility below about 15 K which shows that the temperature dependence of both the static and dynamical spin susceptibilities becomes identical at temperatures not far below the spin-gap energy. | | Source: | arXiv, cond-mat/0402540 | | Services: | Forum | Review | PDF | Favorites | |
