摘要： This paper reports that 9\,nm zincblende CrAs is grown by molecular-beam epitaxy on InAs buffer layer. The zb-CrAs shows ferromagnetism at room temperature and the total magnetic moment $3.09\pm 0.15\,\mu_{\rm B}$ per CrAs unit. The temperature dependence of zb-CrAs resistance $R$ shows metallic behaviour.
