高横向磁场下的μ子自旋弛豫测量[公式：见文本]表明，欠掺杂和铕掺杂（La,Sr）2CuO4和La1.875Ba0.125CuO4的场致准静态磁性强，远高于Tc和TN。Cu自旋极化的磁化率对应，由μ子自旋弛豫率得出，在T约25 K处表现出发散行为。过掺杂La1.81Sr0.19CuO4、最优掺杂Bi2212和zn掺杂YBa2Cu3O7均未检测到磁场感应磁性。
Muon spin relaxation measurements in high transverse magnetic fields [FORMULA: SEE TEXT] revealed strong field-induced quasistatic magnetism in the underdoped and Eu-doped (La,Sr)2CuO4 and La1.875Ba0.125CuO4, existing well above Tc and TN. The susceptibility counterpart of Cu spin polarization, derived from the muon spin relaxation rate, exhibits a divergent behavior towards T approximately 25 K. No field-induced magnetism was detected in overdoped La1.81Sr0.19CuO4, optimally doped Bi2212, and Zn-doped YBa2Cu3O7.
