摘要:

测量了反铁磁轮CsFe_8的~ 1H-NMR谱和核弛豫速率1/T_1,以表征先前观察到的磁场诱导的低温相在8 T的能级交叉附近。数据表明,该阶段的特点是由一个巨大的交错横向极化的电子铁自旋,和开放的差距,提供微观证据的解释相场致磁弹性不稳定性。

英文摘要:

The 1H-NMR spectrum and nuclear relaxation rate 1/T_1 in the antiferromagnetic wheel CsFe8 were measured to characterize the previously observed magnetic field-induced low-temperature phase around the level crossing at 8 T. The data show that the phase is characterized by a huge staggered transverse polarization of the electronic Fe spins, and the opening of a gap, providing microscopic evidence for the interpretation of the phase as a field-induced magneto-elastic instability.
