Abstract

The linear magnetic dichroism in the crystallographically isotropic ab plane of a tetragonal CuB₂O₄ single crystal has been investigated by high-resolution Fourier spectroscopy at temperatures of 1.4–22 K. Magnetic phase transitions are found at T < 2.0 K and their nature is discussed.

Keywords
