Magnetic properties of the Tb1−La MnSi intermetallic compounds at high magnetic field

Magnetic phase transitions in RMnGe (R=Tb, Dy) compounds induced by high magnetic fields

“…And subsequently a linearly growth of the magnetization is observed, but the saturation is not reached. This result clearly demonstrates that we cannot achieve a ferromagnetic ordering either for TbMnGe or for TbMnSi [7] in magnetic fields up to 360 kOe. Consequently the exchange interaction fields between R and Mn sublattices exceed noticeably the applied magnetic field.…”

“…resulting from a rotation of the Mn magnetic moment to the c-axis , however, the complete saturation is not observed since Mn-Mn exchange interaction is stronger than the applied external magnetic field [21]. Also in (La,Tb)MnSi the metamagnetic transition is observed in pristine compound in magnetic field of about 15 T but without saturation [22].…”

“…GdMn(Ge,Ga) alloys show the change of symmetry from orthorhombic TiNiSi-type for GdMnGe to hexagonal ZrNiAl-type for solid solution in which ferrimagnetic structure below TN = 170 K seems to exist. In (La,Tb)MnSi, the change of crystal structure is observed from the orthorhombic TiNiSi to the tetragonal CeFeSi-type as for solid solutions [22]. In turn, for Gd0.6La0.4MnSi two magnetic transitions are observed AF→F→P supposedly both of the 1st order type [24].…”
