摘要：

Standing-spin-wave resonance (SSWR) modes have been observed in an antiferromagnet for the first time. The experiments were performed on MnF 2 films of thicknesses t=0.98 and 0.23 μm, grown epitaxially on carefully polished (001) Mn0.99Fe0.01F2 substrates. An intervening 1.0-μm-thick homoepitaxial, buffer layer of Mn0.99Fe0.01F2 was first deposited to improve both the epitaxial growth and thickness uniformity of the final MnF2 film. The observed SSWR modes exhibit spacings ΔHn appropriate to the boundary conditions in which the spins are pinned at both interfaces. From the spacings of the modes, a value of the spin-wave stiffness constant is obtained which is in good agreement with the calculated value from the known exchange and anisotropy interactions of bulk MnF2.
