“…It is thus apparently different from the magnetic dipole order inferred by earlier theories [7,8]. This mysterious, or hidden, order is an important subject for the study of the actual nature of the ground state of Tb 2 Ti 2 O 7 [9][10][11][12][13][14][15][16][17][18].…”

Abstract. The low-temperature thermodynamic properties of the frustrated pyrochlore Tb 2+xTi2−xO7+y have been studied using the single crystal of x = 0.005 sitting in a long range ordered phase in the x-T phase diagram. We observed that the specific heat exhibits a minimum around 2 K and slightly increases on cooling, similar to a Schottky-like anomaly for canonical spin ices. A clear specific-heat peak observed at T c = 0.53 K is ascribable to the phase transition to a quadrupolar state, which contributes to a relatively large change in entropy, S ≃ 2.7 J K −1 mol −1 . However, it is still smaller than R ln 2 for the ground state doublet of the Tb ions. The entropy release persists to higher temperatures, suggesting strong fluctuations associated with spin ice correlations above T c. We discuss the field dependence of the entropy change for H|| [111] and H|| [001].
