The investigations of low-temperature heat capacity in pure and impurity doped high temperature superconductors have been performed by high-precision pulsed differential scanning calorimeter, providing the measurements of heat capacities under the thermodynamically equilibrium conditions in contrast to commonly used differential scanning calorimeters. The anomaly of low-temperature heat capacity of a wide peak form related with impurity induced static spin correlations was observed.
