Vv. Eremenko et al., NONCOLLINEAR MULTISUBLATTICE MAGNETIC-STR UCTURE OF THE QUASI-2-DIMENSIONAL ANTIFERROMAGNET NH3(CH2)2NH3MNCL4, Fizika nizkih temperatur, 19(7), 1993, pp. 846-849
The exciton light absorption spectrum of NH3(CH2)2NH3MnCl4 is studied
in magnetic fields. It is confirmed that the unit cell of NH3(CH2)2NH3
MnCl4 contains four formula units. It is also shown that its magnetic
structure is noncollinear in the absence of magnetic field.
