摘要：
The optical absorption spectra of single crystals of neodymium and samarium chromium borates are studied. A magnetic phase transition in NdCr3(BO3)(4) (at T-c = 8 +/- 1 K) and SmCr3(BO3)(4) (at T-c = 5 +/- 1 K) is observed. The effective magnetic field acting on the Nd3+ ion from the side of the ordered magnetic subsystem of chromium is estimated.
