摘要：
The mapnetization of the free-powdered intermetallic compound DyMn2Ge2 has been studied in steady (up to 17, T) and Pulsed magnetic fields (LIP to 50T) in the temperature range between 7 and 70K, Several new field-induced magnetic Phase transitions are observed. and the magnetic phase diagram in the field-temperature plane is constructed, In contrast with the single crystal, the free-powdered sample is found to exhibit a mixed state at T<70 and 10T<H-muo<30T. The appearance of a non-collinear magnetic structure in high magnetic fields is found. The existence of an additional field-induced transition in fields above 50T is predicted.
