Abstract
To elucidate from a microscopic point of view the initial evolution of spin fluctuations in TmTe from the semiconducting state at ambient pressure with an antiferroquadrupole ordering (TQ = 1.8K) to the intermediate-valence metallic state at high pressures P≥2 GPa with a ferromagnetic (FM) ordering (Tc ≃ 14 K), we have carried out 125Te-NMR study at pressures P = 0 and 0.9 GPa. The spin-lattice relaxation rate measurements revealed a pronounced increase of the staggered susceptibility below T≃ 14 K, in addition to the Curie-Weiss-type increase of the uniform susceptibility. Below ∼T*, a wipe-out decrease of the NMR intensity and the finding of an unconventional NMR signal around ∼ 10 MHz that is insensitive to applied field lead to the conclusion that a field-induced short-range FM ordering caused by the competition of FM and antiferromagnetic fluctuations takes place. Pressure of 0.9 GPa hardly affects the anomalous NMR behaviors below ∼T*, leading to speculate that the short-range FM ordering in the semiconducting state shares the origin with the long-range FM ordering at≃ 14K in the high-pressure metallic state.

<EA>To elucidate from a microscopic point of view the initial evolution of spin fluctuations in TmTe from the semiconducting state at ambient pressure with an antiferroquadrupole ordering (T<sub>Q</sub>
= 1.8K) to the intermediate-valence metallic state at high pressures P≥2 GPa with a ferromagnetic (FM) ordering (T<sub>c</sub>
≃ 14 K), we have carried out <sup>125</sup>
Te-NMR study at pressures P = 0 and 0.9 GPa. The spin-lattice relaxation rate measurements revealed a pronounced increase of the staggered susceptibility below T≃ 14 K, in addition to the Curie-Weiss-type increase of the uniform susceptibility. Below ∼T<sup>*</sup>
, a wipe-out decrease of the NMR intensity and the finding of an unconventional NMR signal around ∼ 10 MHz that is insensitive to applied field lead to the conclusion that a field-induced short-range FM ordering caused by the competition of FM and antiferromagnetic fluctuations takes place. Pressure of 0.9 GPa hardly affects the anomalous NMR behaviors below <sup>∼</sup>
T<sup>*</sup>
, leading to speculate that the short-range FM ordering in the semiconducting state shares the origin with the long-range FM ordering at≃ 14K in the high-pressure metallic state.</EA>
