Frustration and short range magnetic correlations in the pyrochlore Y2Mn2O7 (abstract)
Abstract
The bulk magnetic susceptibility of Y2Mn2O7 is suggestive of ferromagnetic order, θc=+40 K, apparent Tc=25 K. However, both dc and ac susceptibility data show a broad maximum near 6 K which is frequency and field dependent. Heat capacity studies to 2 K show no evidence for long range magnetic order. Also, neutron scattering data indicate the presence of short range correlations. These results are compared to mean field theory predictions for …
