Complex magnetic states of heavy fermion compound CeGe
The intermetallic compound CeGe exhibits unusual magnetic behavior due to the interplay between the Kondo and the antiferromagnetic coupling. This particular system is interesting because the Kondo temperature is close to the Néel temperature, resulting in a close competition between the low-tempe...

| description |
The intermetallic compound CeGe exhibits unusual magnetic behavior due to the interplay between the Kondo
and the antiferromagnetic coupling. This particular system is interesting because the Kondo temperature is close to
the Néel temperature, resulting in a close competition between the low-temperature interactions, which can be
tuned by means of varying external parameters such as pressure and applied magnetic field. Interestingly, magnetization
measurements up to 12 kbar reveal that the Néel temperature is not affected by pressure. Measurements of
the electrical resistivity, however, show that the sharp upturn appearing below TN is sensitive to pressures up to
15 kbar. This suggests that pressure may change the complex antiferromagnetic spin structure. The validity of an
explanation based on the magnetic superzones seen in the rare earths is discussed here.
