  We present numerical and analytical results for the swiching times of
magnetic nanoparticles with uniaxial anisotropy at elevated temperatures,
including the vicinity of T_c. The consideration is based in the
Landau-Lifshitz-Bloch equation that includes the relaxation of the
magnetization magnitude M. The resulting switching times are shorter than those
following from the naive Landau-Lifshitz equation due to (i) additional barrier
lowering because of the reduction of M at the barrier and (ii) critical
divergence of the damping parameters.
