S=3/2反铁磁蜂窝晶格化合物Bi3Mn4O12(NO3)的无序基态和磁场诱导长程序

摘要:

Bi_3Mn_4O_(12)(NO_3)是第一个没有长程磁有序的蜂窝晶格体系,其中Mn ~(4+)离子携带S=3/2。利用中子散射,我们已经确定,短程反铁磁相关发展在低温下。外加磁场会引起磁性转变,即短程有序突然扩展为长程序。

英文摘要:

Bi3Mn4O12(NO3), in which the Mn4+ ions carry S=3/2, is the first honeycomb lattice system that shows no long-range magnetic order. Using neutron scattering, we have determined that short-range antiferromagnetic correlations develop at low temperatures. Applied magnetic fields induce a magnetic transition, in which the short-range order abruptly expands into a long-range order.
