Structure of the metalorganic magnet in three planes; the unit cell is outlined. The heavy lines show the paths of the exchange interaction .
Temperature dependence of the magnetic susceptibility of the single crystal for an orientation of the external magnetic field along the axis. The inset shows the low-temperature part of the curve. The data points are experimental, the lines theoretical: the solid curve for the 1D model and the dotted lines for the 2D model (see text).
Frequency–field diagram of the AFMR spectrum of at in the field ranges 0– (a) and 0– (b).
Form of the EPR absorption spectrum in at a frequency of for ; . At half field one can see an additional absorption of low intensity. The external field is oriented in the plane.
Shape of the STA absorption band in along the easy axis . The absorption below the hydrazyl line is the AFMR line at the spin-flop mode at frequencies of 32.71 (a) and 33.77 (b).
Frequency–field dependence of the AFMR bands and STA in at : the solid lines are the ARMR spectrum; the shaded areas are the existence region of the sum STA bands. The experimentally observed sum bands of the STA are shown schematically here.
Shape of the absorption band in at at frequencies of 28.82 and . . The numbers denote: 1—two-magnon absorption, 2—hydrazyl, 3—homogeneous resonance, 4—three-magnon absorption, 5—homogeneous resonance (the branch that softens at ).
