Abstract:

Tm2Co17 is a ferrimagnet with T-C = 1170 K and, at 4.2 K, has a spontaneous magnetic moment M-s = 13.4 mu(B)/f.u. Magnetization curves were measured on a Tm2Co17 single crystal along the principal axes in pulsed magnetic fields up to 70 T at 4.2 K. The curve along the easy {[}001] direction exhibits a distinct anomaly at mu H-0(cr)=39 T, where the magnetization exhibits a stepwise rise from M-s to M-flip=40.6 mu B/f.u. The observed transition from the ferrimagnetic ground state (with M-s=17 mu(Co)-2 mu(Tm)) to a saturated spin-flip state with parallel orientation of the sublattice moments and M-flip=17 mu(Co)+ 2 mu(Tm) is unusual for 3d-4f intermetallics because it does not proceed via an intermediate angled-sublattice state. Rather, a collinear remagnetization of the Tm sublattice takes place: as the applied magnetic field grows, the Tm moments disorder at first, reaching a fully disordered paramagnetic state at H=H-cr, then they order magnetically in the opposite sense.
