摘要：

By means of the recently developed algorithm based on the tensor product states, the magnetization process of frustrated spin-1/2 spin-dimer models on a square lattice is investigated. Clear evidence of a supersolid phase over a finite regime of magnetic field is observed. Besides, critical fields at various field-induced transitions are determined accurately. Our work hence sheds light on the search of the supersolid phase in real frustrated spin-dimer compounds.
