  Pyrochlores offer an ideal playground to investigate the magnetic ground
state of frustrated magnetic systems. In this class of materials, competition
between various magnetic interactions remains frustrated and prevents an
ordered magnetic state at low temperatures. Tb2Sn2O7 has recently attracted
significant attention due to its ordered spin-ice state. Additionally, in such
systems, application of external magnetic field might result in exotic magnetic
states. Our current investigation on Tb2Sn2O7 reveal the presence of a new
phase associated with fifth order susceptibility at low temperatures and high
magnetic fields. In this compound, at zero fields, for a stabilized spin-ice
state, the singlet-singlet state separated by {\delta} play an imperative role.
Under magnetic fields, {\delta} increases and the Zeeman energy associated with
the magnetic anisotropy is believed to get enhanced; which can be the key
ingredient for evolution of higher-order moments, above 10 kOe, in this
compound.
