Title

Magnetic correlations in Tb2+xTi2-xO7

Abstract

We propose to study the mesoscopic magnetic structure with K= ½ ½ ½ propagation vector in Tb2+xTi2-xO7 pyrochlore for a slight off- stoichiometry (x=-0.01) pyrochlore. According to a recent report, this exotic order (in principle forbidden by fcc translations) is tuned by minute changes of the Tb content. It appears below 0.4K and coexists with the liquid fluctuations down to T=0, where it involves a low ordered moment. Our previous results in 2013 (CRG exp.) intended to measure 3 samples ( X=0, 0.01, -0.01) but the last sample was not measured due to a failure of the electronics. The full study will allow to check the evolution of the anomalous correlations throughout the phase diagram.
