摘要：
Spintronic terahertz emitters are terahertz wave emitting elements that utilize spin currents. We have produced Pt/Co spintronic terahertz emitters by epitaxial growth of Pt and Co layers on MgO(110) substrate. The azimuthal angle dependence of Pt/Co spintronic terahertz emission shows characteristic dependences due to magnetic anisotropy. The terahertz emission is useful to evaluate the magnetic anisotropy in spintronic thin films.
