Magnetic Susceptibility for $CaV_4O_9$
Ken’ichi Takano ; Kazuhiro Sano ;
Date 13 May 1998
Subject cond-mat
AbstractWe examine experimental magnetic susceptibility $chi^{tot}(T)$ for CaV$_4$O$_9$ by fitting with fitting function $alpha chi^{mag}(T) + c$. The function $chi^{mag}(T)$ is a power series of 1/T and the lowest order term is fixed as $C/T$, where $C$ is the Curie constant as determined by the experimental $g$-value (g=1.96). Fitting parameters are $alpha$, $c$ and expansion coefficients except for the first one in $chi^{mag}(T)$. We determine $alpha$ and $c$ as $alpha simeq$ 0.73 and $csimeq$ 0 for an experimental sample. We interpret $alpha$ as the volume fraction of CaV$_4$O$_9$ in the sample and $chi^{mag}(T)$ as the susceptibility for the pure CaV$_4$O$_9$. The result of $alpha e 1$ means that the sample includes nonmagnetic components. This interpretation consists with the result of a perturbation theory and a neutron scattering experiment.
