High-field magnetization of single crystals CeCu2X2 (X=Si and Ge) and YbCu2Si2

Abstract: High-field magnetization measurements of ( and Ge) and were carried out up to 50T. The magnetization of at 1.3K increases linearly, with a small metamagnetic transition at 7.8 and 10.5T for H//[110] and [100], respectively, and saturates at 27T for H//[100] and [110], while the magnetization also saturates at 15.5T for H//[001], without the metamagnetic transition. The high-field magnetization of at 1.3K shows no metamagnetic transition. [Copyright &y& Elsevier]
