我们测量了垂直磁场中硅中低无序、强关联二维电子系统的热力学磁化强度。一个新的，无参数的方法是用来直接确定的频谱特性（朗德g因子和回旋质量）时，费米能级位于光谱间隙和准粒子之间的能级间相互作用被避免。层内相互作用被发现强烈修改的磁化，而不影响确定的g（*）和m（*）。
We measure the thermodynamic magnetization of a low-disordered, strongly correlated two-dimensional electron system in silicon in perpendicular magnetic fields. A new, parameter-free method is used to directly determine the spectrum characteristics (Lande g factor and the cyclotron mass) when the Fermi level lies outside the spectral gaps and the interlevel interactions between quasiparticles are avoided. Intralevel interactions are found to strongly modify the magnetization, without affecting the determined g(*) and m(*).
