我们报告了稀土金属四硼化物TbB 4的高场磁化和磁致伸缩测量，其中Tb矩在四方底面形成Shastry-Sutherland晶格。当磁场垂直于易磁化面时，出现多个磁化平台。我们认为，磁化平台是由独特的二维网络中的磁阻挫和四极相互作用的综合效应引起的。
We report high-field magnetization and magnetostriction measurements on the rare-earth-metal tetraboride TbB4, in which the Tb moments form a Shastry-Sutherland lattice in the tetragonal basal plane. A number of magnetization plateaus appear when the magnetic field is perpendicular to the magnetic easy plane. We propose that the magnetization plateaus arise from the combined effect of magnetic frustration and quadrupole interaction in the unique two-dimensional network.
