Nearly single-phase samples of compound TbCo{sub 5+{delta}} (where {delta} = 0) are obtained and certified in the poly-and monocrystalline state. The latent heat is measured on these samples for the first time in the region of the spin-reorientation phase transition using differential scanning calorimetry. The latent heat of the transition is found to be 1.3 {+-} 0.2 kJ/kg. The experimental data are compared with the theoretical results obtained in the framework of the single-ion theory (Q{sub L} = 1.1 kJ/kg). It is found that the discrepancy is insignificant to within the experimental error.
