      abstract     = {Using first-principle calculations in conjunction with the
                      frozen-magnon technique we have calculated the exchange
                      interactions and spin-wave dispersions in the series of the
                      zincblende half-metallic II-V (CaZ, Z = N, P, As, Sb)
                      ferromagnets. The calculated exchange constants are used to
                      estimate the Curie temperature within the random phase
                      approximation. The large Stoner gap in these alloys gives
                      rise to well-defined undamped spin waves throughout the
                      Brillouin zone. Moreover we show that the spin-wave
                      stiffness constants for the considered systems are among the
                      largest available for local moment ferromagnets. The
                      predicted Curie temperature of half-metallic CaN is
                      noticeably higher than the room temperature with respect to
                      the other compounds, and thus we propose CaN as a promising
                      candidate for future applications in spintronic devices.},
