摘要：
We present macroscopic magnetic measurements on single crystals of the nonferromagnetic alpha' modification of TDAE-C-60 in a wide temperature (2 K <T<100 K) and field (O<H<50 kOe) range. Results show that the low-temperature magnetic properties of alpha'-TDAE-C-60 can be described in terms of simple paramagnetic model of noninteracting spins with the effective number of spins corresponding to one Bohr magneton mu(B) per formula unit. The effective number of spins gradually increases from one to two mu(B) per formula unit as the temperature rises towards 100 K. We propose a model of two independent magnetic subsystems with different spin interactions which could account for the observed magnetic behavior of alpha'-TDAE-C-60.
