Magnetic properties of amorphous Er{sub 1{minus}{ital x}}Fe{sub {ital x}} alloys with {ital x}{approx_equal}0.7 have been studied. Macroscopic characterization has been performed by measuring temperature- and field-dependent magnetization. Applying a magnetic field the compensation temperature first decreases, but increases again at larger fields. This {open_quote}{open_quote}exotic{close_quote}{close_quote} behavior has been interpreted in terms of the sperimagnetic character of both subnetworks. The suggested scheme has been checked by measuring x-ray circular magnetic dichroism at the Er {ital M}{sub 5}-edge. Using this atom-sensitive technique we have been able to detect temperature-induced as well as field-induced flips of the Er-subnetwork with respect to the direction of the applied field. {copyright} {ital 1996 American Institute of Physics.}
