摘要：

Submillimeter spectra (10-100 cm-1) were measured for the first time in the orthorhombic antiferromagnet dicalcium ferrite Ca2Fe2O5 in zero magnetic field. Two magnon modes have been observed by means of Fourier spectroscopy at temperatures 4.2-350 K. Experiments indicate that the effective anisotropy fields in the ca- and cb-planes differ by more than an order of magnitude.
