Gapped and gapless short-range-ordered magnetic states with (12,12,12) wave vectors in the pyrochlore magnet Tb2+xTi2−xO7+δ
Abstract
Recent low-temperature heat capacity (CP) measurements on polycrystalline samples of the pyrochlore antiferromagnet Tb2+xTi2−xO7+δ have shown a strong sensitivity to the precise Tb concentration x, with a large anomaly exhibited for x∼0.005 at TC∼0.5 K and no such anomaly and corresponding phase transition for x≤0. We have grown single-crystal samples of Tb2+xTi2−xO7+δ, with approximate composition x=−0.001,+0.0042, and +0.0147, where the …
