Query: Thermo-magnetic hysteretic properties resembling superconductivity in
  the normal state of La1.85Sr0.15CuO4   We have performed detailed magnetic and thermal hysteresis experiments in the
normal-state magnetization of La1.85Sr0.15CuO4 single crystal. Using a
combination of in-field and in-zero-magnetic-field measurements at different
stages of thermal history of the sample, we identified subtle effects
associated with the presence of magnetic signatures which resemble those below
the superconducting transition temperature (Tc=36 K) but survive up to 250 K.
