Abstract:
The linear magnetic dichroism in the crystallographically isotropic $ab$ plane of a tetragonal CuB$_{2}$O$_{4}$ 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:magnetic dichroism, Fourier spectroscopy, magnetic phase transitions.
