FIG. 1.

Temperature dependence of the magnetic moment projection on the -axis for the sample No. 1 at different applied magnetic fields . Triangular hysteresis is seen below 25 K at and . The “butterfly pattern” between 40 and 60 K marks the first order transition at the compensation point.

FIG. 5.

Magnetic moment of (sample No. 1) in a weak external field above and below . Triangular hysteresis occurs at the same value of magnetization on both sides of the compensation point. Inset: hysteresis loops in the interval of the triangular temperature hysteresis above exhibit a triangular-tail shape similar to those found in the hysteresis interval below (Fig. 2). In both cases these loop shapes determine the triangular shape of the hysteresis.
