The half-lives of 20 neutron-rich nuclei with Z=27-30 have been measured at the RIBF, including five new half-lives of Co76(21.7-4.9+6.5ms), Co77(13.0-4.3+7.2ms), Ni79(43.0-7.5+8.6ms), Ni80(23.9-17.2+26.0ms), and Cu81(73.2±6.8ms). In addition, the half-lives of Co73-75, Ni74-78, Cu78-80, and Zn80-82 were determined with higher precision than previous works. Based on these new results, a systematic study of the β-decay half-lives has been carried out, which suggests a sizable magicity for both the proton number Z=28 and the neutron number N=50 in Ni78.
